A self-tapping screw is a screw which can tap its own hole as it is driven into the material.

Common features are the screw thread covering the whole length of the screw from tip to head and a pronounced thread hard enough for the intended substrate, often case-hardened

Some self-tapping screws are also self-drilling, which means that, in addition to the tap-like flute in the leading threads, there is also a preliminary drill-like fluted tip that looks much like the tip of a centre drill. These screws combine a drilling action and the fastener installation itself into only one driving motion (instead of separate drilling, tapping, and installing motions); they are thus very efficient in a variety of hard-substrate applications, from assembly lines to roofing.

As products are increasingly utilising multi material assemblies, it has become important to understand the various options and processes available for joining the same. A common and useful method is using blind rivets which allow fast and convenient assembly.

However, when joining soft or low density materials like plastics, wood, fabric etc., the rivet head can pull through during fastening or application of load. Therefore it is important to select the correct type of rivet and process.

A rivet with a large Flange head is a good option in many cases where a soft part is to be fastened to a hard part with the large flange abutting the soft side. There are also new designs available which are better suited for such applications.

 

The PEEL blind rivet is one such type of blind rivet. On setting the body splits into several parts, assuring a good fastening on soft or irregular surfaces.

Sheet Metal Screws for Wood - Not a Good Idea

BrandEXPANDET

Do NOT use self-tapping screws for fixing into wood. It is a common error whereby many people use self-tapping screws for fixing into wood. Self-Tapping screws are designed for use in metal. For that purpose the threads are closer and of shallow depth. This works well in metals like steel and aluminium.

However, in wood the material density is low and such thread profile would easily lose their grip. Therefore wood screws or chipboard screws need to be used.

 

Wood screw threads have more depth and a wider pitch. This enables the threads to cut deeper into the base material and hold more of the wood when installed.

Using wood screws for metal is also not recommended as the threads can strip out. There would also be higher stress on the base material and the screw because of the higher thread depth.

 

A number of innovations have taken place in the design of wood screws and it is worthwhile to consider these when making a selection.

It is common belief that a simple test for stainless steel is to check with a magnet. If it attracts, the product is not stainless steel. However, this assumption is incorrect. All cold worked Stainless Steel Fasteners get magnetised. The extent of magnetism induced varies for different grades and is explained in ISO-3506-2.

Unless you need a fastener which is used in a product like medical MRI instruments wherein any magnetism affects the results, you may select the grade suitable for corrosion resistance as necessary for your application. For certain highly sensitive instruments wherein the function is affected by magnetism of any of the assembly components, alternative materials like Titanium or Non-Metallic fasteners may be selected.

For corrosion resistance, the properties of stainless steel 300 series are unaffected by the extent of magnetism in the fastener.

Understanding The “Big Box” – It is important not fixate on the cost of any single component but rather on the entire fastened joint. In other words, it is all too common for the user to focus on a single component and ignore all that is going on with the entire fastened joint.

Take for example the simple act of attaching a cover over an aluminium housing. There are many approaches that can be taken to accomplish this, but perhaps the most traditional approach would be to tap threaded holes in the aluminium housing and use a simple machine screw to make the attachment. Now, “what if you changed those screws to thread rolling screws?” or “why not use a thread insert as reinforcement?”. A near sighted answer would be “no we can’t do that because it will cost more.”

GALLING - The Bane Of Fastener Failure

REQUEST CALLBACK

Ask for Price

Product Price: Ask Latest Price

Product Details:

MaterialStainless Steel

Thread galling is a common, yet seldom understood problem with threaded fasteners. Galling, often referred to as a cold-welding process, can occur when the surfaces of male and female threads are placed under heavy pressure. The frustrating aspect of fastener galling is that galled nuts and bolts may pass all required inspections (threads, material, mechanical, etc.), yet they still fail to function together.

 

Minor galling may cause only slight damage to the thread surface and the installer may still be able to remove the fastener. However, in severe cases galling can completely weld the nut and bolt together and prevent removal of the fastener.

If the tightening process is continued once galling begins, the fastener may be twisted off or have its threads stripped.

It most commonly occurs in fasteners that are likely to be subjected to a lot of motion, such as those that are meant to be fastened and undone regularly, or those that are subjected to regular vibration.

 However, there are times when the galling can occur during the initial fastening as well. 

Consequences of Thread Galling.

Potentially disastrous effects could result from galled fasteners seizing or experiencing fatigue breakage. It can increase maintenance and repair costs, as the galled or broken fasteners need to be removed and replaced, and the holes where the fasteners are applied may need repairs. And if features on fasteners that promote galling are not eliminated or mitigated, they may not only chronically affect the equipment, but the assembly line also, exposing it to recurring delays, downtime, and occupational hazards. 

 


 At worst, fatigue breakage of critical fasteners might result in accident or injury. Galled fasteners are also much more susceptible to corrosion, which can ultimately result in breakages.

Ways to minimize galling.

 

Add fastener lubricationThe most efficient way to minimize risk of galling is to add an anti-seize solution.  Make sure the correct anti-seize is used based on the environment.
Reduce installation speedAs installation increases friction can cause a fastener to get hotter and hotter, reduce the speed will not stop the chance of galling completely but it will allow the heat to dissipate.
Take load off assembly before tighteningWhen tightening the nut onto the bolt, ensure there is no or minimal load on the assembly. 
Use a torque wrench to avoid over-torqueOver-torqueing a nut can cause damage to the threading.
Use two different grades of the materialSome success has been found by using one softer grade and one harder grade material. 
Ensure fastener threads are not damaged prior to installationDamaged threading will increase the friction during installation.
Ensure there is no debris in fastener threading prior to installationDebris sitting inside of threading will also greatly increase friction during installation. If bolts are covered in dirt use compressed air to remove it before use.
Use coarse threading where possibleFine threaded fasteners are great tools but require many more turns per inch during that coarse threading. This, in turn, will generate more friction per inch leading to an increased chance of galling.
Keep fasteners in a controlled environmentTry to keep fasteners in a cool environment. If left in the sun, the fasteners will heat up resulting in an increased chance of galling.

If seizing begins, immediately stop and remove the nut and bolt, use new fasteners and apply lubricant.

 The need to safeguard against theft and vandalism in now becoming an essential part of design specifications.

Why Use Tamper Resistant or Tamper Proof Screws?

Tamper resistant screws’ purpose is in making security violations challenging. They thwart opportunistic attacks but offer slight defence against deliberate intentions. If someone’s bent on entering or removing an object, they’ll find a way. You can say tamper resistance is a first-line, but low-level, security measure.

Common Uses for Tamper Proof Bolts and Screws

Primarily anti-tampering fasteners are used to deter people from trying to remove them. Here are some common uses for tamper proof securing products:

·    Access points ·   Computers ·  Consumer product displays ·   Digital cameras ·   Electrical devices

·  Engine components ·  Glass panels and Hinges

·  Inmate furnishings ·  License plates and Wheel Locks

·  Manholes, Waste Bins and Park Benches

·  Outdoor play equipment ·  Safety rails, Signs and Scaffolding 

How to Choose the Right Tamper Proof Screw

Choosing the right tamper proof screw depends on what you’ll use it for and where you intend to place it. Choosing the right screw depends on four main factors:

 The security level you desire

Tamper Resistant Screws are the starting level with some designs that are now being produced in many countries and availability of removal tools easier than before. They do however provide the first line of defence and deter the casual vandal and also a user who may not open the product for self-maintenance.

Example of this design is the PIN-HEX.A higher level of security is obtained by different designs like the 6-Lobe or PIN-TORX and Two-Hole or Snake-Eye designs.

The availability of removal tools is lesser and production costs higher.

 Whether you intend to remove them or not

Permanent security fasteners do not provide the facility of reuse and have to be broken to open.

These are Tamper-Proof options. The One-Way Screws which is a low torque fastener tightened using a normal screw-driver is one such example.

Shear Bolts and Shear Nuts which provide a very high level of security andinstalled with a standard spanner are another option. 
Removable Security Fasteners need special tools for installation and removal of the fastener.

These are non-permanent types. The Pin-Hex, Pin-Torx, Two-Hole, 5-Lobe are examples of such screws.

 KMR Nuts are reusable nuts.

 How much strength you require for the assembly.
Due to the design constraints, many security fastenings are not suitable for very high torque applications.

For low torque applications, the One-Way, Two-Hole and PIN-HEX drives are suitable and for medium to high torque applications, the 6-Lobe-Pin and 5-Lobe-Pin drives are better.  The Shear Bolts and nuts can be customised for medium to high torque applications.
What finished appearance or look you intend to display.

This is an aesthetic call that the designer has to make while balancing the security level, strength and cost. The Two-Hole or Snake Eye design is preferred for an aesthetically pleasing finish.

Premium security screws

For high security usage a premium security fastener is the best option. These have a complex drive design and are installed and removed using a special tool that is not available in the traditional outlets.

TIP: When your assembly requires a bolt-nut solution, consider using a Blind Rivet Nut on one side to make it non-removable. This allows you the flexibility of selecting a suitable tamperproof screw.

Plastic is proving to be a versatile material for the future in spite of the hue and cry against it. It is opening up a world of innovations where smaller, lighter and cheaper is driving the markets. But it comes with its own technological challenges such as suitable fastening solutions. The regular screws are completely unsuitable leading to development of specialised screws for use in plastics.

Fastening plastics using standard self-tapping screws frequently causes assembly problems. The plastic material is liable to burst due to stresses that build up in the assembly.

One solution is inserting the screws into metal inserts but this adds to the procurement and assembly costs.

Fastening thermo plastic materials during construction and assembly as well as their load capacities prove to be challenging issues for industrial users on a regular basis.

With the increasing use of 3D printing technology, it has become imperative that a reliable screw capable of providing a secure strong joint in plastics is available.

Selecting the Right Fastener

With thousands of different polymers available today, there can be no absolute guidelines to follow when fastening these materials.

The dynamics of plastic vary according to the type of plastic used. The screw selected needs to take into account the thermal expansion, clamp retention and tractile capability of the material.

For maximum performance, a fastener should be selected early in the design process. 

Proper fastener selection may allow the use of thinner bosses and eliminate the need for supplementary locking devices. This can reduce in-place costs through:

  • Reduced material usage
  • Reduced cycling times
  • Elimination of inserts and adhesives
  • Streamlined assembly.

Fasteners specially designed for plastics can optimize performance in specific types of materials. By selecting the proper fastener, you may obtain:

  • Higher strip-out torque values
  • Increased resistance to loosening
  • Higher pull-out values

Thread Forming Screws. Screws that deform the base material to form their own threads are called thread forming screws. TheY deform a lot of plastic when they are driven. This produces a high resistance to back-out but also creates large concentration of stresses in the material. For harder plastics, this can result in failure.

An effective solution is to use thread-forming screws with 30° thread form.

This feature allows the screw to make deeper grooves into the material and capture more of it between the threads, creating an even greater resistance to shear force while reducing stress.

The JCPlas screw uses this design form which provides many benefits like:

  1. Optimal connection of plastic parts
  2. Minimal radial stress
  3. Considerably increased durability of screw connection in static and dynamic tensile loading.
  4. Low thread forming torque ensuring safety of the plastic recipient
  5. Elimination of the risk of relaxation
  6. A guaranteed tenfold re-assembly
  7. The thread’s one-of-a-kind geometry results in an optimal fastening and self-locking mechanism for thermoplastics.

 

  1. Increases preload force by higher flank overlapping on pressure side
  2. These Screws with large than normal threads increase the load bearing capacity of the plastic and provide high quality internal threads with no damage to the molecular structure of the plastic, significantly reducing the danger of material failure.
  3. Fast, cost-effective application.
  4. The easy starting, easy driving capabilities of JCPLASscrews cut assembly time and costs.
  5. Exceptional holding power eliminates the need for thread inserts.

COMPARATIVE ANALYSIS OF STAINLESS AND COATED CARBON STEEL FASTENERS

Corrosion of stainless and carbon steel are very different, and this guidance provides information regarding general attack or surface corrosion as this is often a primary consideration when selecting fastener material.

Carbon and stainless steel are the most common materials from which fasteners are manufactured and each is available in hundreds of alloys or grades with a wide variety of attributes.

Initial cost of a stainless steel component is generally higher than carbon steel though not always. Secondary processes, such as heat treating or plating, often add to the cost of carbon steel parts when they may not be incurred with stainless steel.
Cost is meaningless without consideration of value. The ‘value’ of a fastener that provides maximum quality may offset any associated cost increase. Designers must weigh cost, benefit, and risk when choosing the appropriate fastener material.

Though carbon and stainless steel are both ferrous metals, their response to corrosive attack is much different. By definition stainless steel must contain at least 10.5% chromium. When exposed to oxygen this alloying element creates a layer of chromium oxide at the surface that quickly stops growing thus becoming ‘passive’. This passive layer is continuous, uniform in thickness, insoluble, and nonporous. The passive layer prevents contact between oxygen in the environment and base metal and will self heal if scratched or abraded as long as oxygen remains available.

Rust occurs in iron and iron alloys such as steel. Rust is a layer of iron oxide created at the surface of a part when exposed to oxygen in the presence of moisture. This layer of iron oxide remains active and continues to convert iron to iron oxide as the outer layers lose integrity and fall away exposing new metal.

MaterialSTAINLESS STEEL
BrandEXPANDET

Wooden decks usually consist of thin planks; being outdoors, they must endure harsh environmental conditions.

 

The most important construction materials are often the smallest. Although you do need all your heavy elements like power tools, cement, wood, and other building materials, it often comes down to the smallest element to bring all of these together. And the smallest elements, in this case, are decking screws. And often, for the best possible finish, you will need the best decking screws.

They are designed to resist corrosion, drive easily and lay smoothly against the deck surface. As they anchor timber or composite deck boards to structural timber or joists, to ensure a good smooth working, these screws have a parallel shank, with a self drilling and countersink feature. This enables the screw to be fastened in a single operation doing away with the necessity of predrilling the deck boards.

Usually made from stainless steel or with a SS coating to prevent corrosion for outdoor use, its other special feature includes a high torque drive fitting such as hexagon, square and torx drives.

Many people do not realize there is a difference or that they even need a special screw for the top of the deck; however, deck screws can be very important to the overall look of a deck. These screws are manufactured with aesthetic appeal in mind, as they will remain uncovered and visible within the deck boards. It is important to install deck screws correctly to ensure the beauty and structural stability of the deck.

Carbon and stainless steel are the most common materials from which fasteners are manufactured and each is available in hundreds of alloys or grades with a wide variety of attributes.

Initial cost of a stainless steel component is generally higher than carbon steel though not always. For example – material is a smaller component of cost in a light duty Coiled Pin than it is in a Solid Pin of the same diameter and length. As a result the stainless steel Coiled Pin may be available at equal or lesser cost than the carbon steel Solid Pin. In addition, secondary processes, such as heat treating or plating, often add to the cost of carbon steel parts when they may not be incurred with stainless steel.

 

Cost is meaningless without consideration of value. For example, the manufacturer of an outdoor barbecue grill may select stainless steel fasteners capable of resisting corrosion much longer than the product’s expected life span. This selection would demonstrate commitment to product integrity, cosmetic appearance, and long life.

The ‘value’ of a fastener that provides maximum quality may offset any associated cost increase. Designers must weigh cost, benefit, and risk when choosing the appropriate fastener material.

Though carbon and stainless steel are both ferrous metals, their response to corrosive attack is much different. By definition stainless steel must contain at least 10.5% chromium. When exposed to oxygen this alloying element creates a layer of chromium oxide at the surface that quickly stops growing thus becoming ‘passive’. This passive layer is continuous, uniform in thickness, insoluble, and nonporous. The passive layer prevents contact between oxygen in the environment and base metal and will self heal if scratched or abraded as long as oxygen remains available.

The passive layer is only 10 to 100 atoms thick and as such has no dimensional impact on parts. Though stainless steel can corrode when exposed to some chemical agents under specific conditions, it will not rust by uniform or general attack as does carbon steel.

As an alloying element, the chromium is part of a homogenous blend and is deemed safe as it cannot be easily liberated from the alloy.

Stainless steel is 100% recyclable and industry analysts estimate 80-90% of discarded stainless steel is captured for recycling.

Rust occurs in iron and iron alloys such as steel. Rust is a layer of iron oxide created at the surface of a part when exposed to oxygen in the presence of moisture. This layer of iron oxide remains active and continues to convert iron to iron oxide as the outer layers lose integrity and fall away exposing new metal.

Iron oxide is also porous allowing it to absorb moisture and elements that may contribute to corrosion thus extending the period of active corrosion with each exposure. To prevent the formation of iron oxide or rust it is necessary to eliminate exposure to oxygen and moisture.

Product Details:

Drive TypeTorx
MaterialStainless Steel

Upgrade your product assembly by switching over to Hexalobular or Torx drive Screws.
The hexalobular socket screw drive, known as Torx or star drive, uses a star-shaped recess in the fastener with six rounded points.
It’s designed to permit increased torque transfer from the driver to the bit compared to other drive systems. Radial forces are drastically reduced resulting in longer tool life. It has vertical sidewalls which increases tool engagement.
Torx Screws do not have camout problems as no camout forces are created to push the driver up and out of the fastener recess. Due to this, the pressure required to keep the screwdriver in the socket reduces significantly and therefore reduces operator muscular stress and fatigue.

Advantages

Higher torque transfer

The driving forces are transferred through surfaces rather than through edges. This results in less wear and tear on tools and no damage to the surface treatment – the corrosion protection like plating or passivation is preserved.

Longer tool life

The optimal torque transmission extends the working life of screwdriving tools. This leads to considerable cost savings, above all when working with small screws or socket set screws. There is no «came out» effect typical with cross recess drive screws.

Large potential for rationalisation

One type of drive can be used for many different types of screw. This particularly applies to the size range up to M8. The product range used can be reduced. The logical result is less outlay on assembly tools and reduced storage and logistics costs.

Possibilities of slimmer heads

The high torque transmission opens up new possibilities for special shapes – a tool for different dimensions. Problems associated with installing low head or flat head screws are virtually eliminated.

Development of the SLIM – Ultra Low Profile screw is one such example.

Because of these advantages, Torx drive screws are very popular in the automotive and electronics industries.
