• 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.

• 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.

Increases preload force by higher flank overlapping on pressure side   

• 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.

10.  Fast, cost-effective application.

11.  The easy starting, easy driving capabilities of JCPLAS screws cut assembly time and costs.

12.  Exceptional holding power eliminates the need for thread inserts.

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

A Self-Drilling Screw is a Self-Tapping Screw with the added feature of a drill point. The drill point looks a lot like the point of a drill. It will drill a hole and form the mating threads in one operation.

 

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.

 There are various types of Self-Drilling screws available with us suitable for a number of applications.

The Phillips PAN head style is the most common useful for most applications.

For Extreme service conditions, AISI 316 grade stainless steel screws are used. These provide a very long life to the installation even in coastal areas.

A self-tapping thread-cutting screw would typically be used in wood or metal, and it cuts material out of its way as it enters and drives inward.
Self-tapping screws are normally made either from carbon steel or stainless steel, but they have other qualities that change their appearance and chemical composition. Stainless is the most commonly found screw material, often chosen for its corrosion resistance and is made with varying strengths that depend on the amount of nickel, chromium and other alloys they contain.
Self tapping screws are normally used with sheet metal and plastics. This variant has a hexagon head, so is designed to be driven in with a standard spanner or ratchet and socket. As the name suggests, this type of screw forms its own thread as it is installed into a pre-drilled hole.

Self-tapping screws are commonly used when you need to attach two pieces of material together where you can only access one side of the material. Where you can access both sides you can use either a screw or a bolt.

Self-tapping screws are useful where you have to disassemble and reassemble products such as furniture, as self-tapping screws will relocate themselves into the same threads which they have been removed from.

Chipboard screws, also called speed screws, are developed to prevent the problems arising with the application of the conventional wood screws in chipboard and different type of wood.

This type of screw can be used in chipboard and soft wood types without pre-drilling, due to its thin core diameter and sharp angle of the thread.

This sharp thread cuts into wood with lower splitting effects, while simultaneously reducing the insertion torque. This combination increases the battery life on the used power tools and has the advantage of saving production time. The pull-out forces are also more consistent from the reduced splitting. These are normally available fully threaded. Half thread also available.

Wood screws are probably the most commonly-used mechanical woodworking fasteners. They are used primarily for connecting wood to wood and are known for the clamping force that they provide to strengthen a joint. They can also be used to attach hinges, hardware, locks, and other non-wood objects.

There are many different types of screws, but only certain types are applicable for woodworking. While all wood screws have an aggressive thread for grabbing and holding the wood, there are many differences in the varieties of wood screws, based on the gauge, length, head type, and drive type of the screw in question.

Head Types

The two most common head types for wood screws are slotted, commonly referred to as flathead, and Phillips, sometimes referred to as cross-head.

Our range is from 2.5mm to 6.4 mm diameter screws in slotted type as per DIN 97

It is a common error in assuming that Stainless Steel Self Drilling Screws will drill into steel. However, that is not the case. To provide corrosion resistance, stainless steel self-drill screws are made from AISI-304 or AISI-316 grades. These cannot be hardened and therefore the drill point can only drill into softer materials like Aluminium. For fixing onto steel structures, Bi-Metal self-drilling screws have been developed. These screws have a carbon steel tempered drill point welded onto a stainless steel shank. This design enables the dual advantages of 1) self-drilling through hard metal sheet up to 12mm and 2) corrosion resistance on the stainless shank 3) drilling, tapping and fastening in one shot. Besides, the induction heat treatment on drilling point, which avoid sensitization of the stainless steel material on the shank.

The reliable Self-Tapping screw for easy fastening into Metal and Plastic.

We have added PT screws – Self-Tapping Screws suitable for both plastics and metal. With a blunt type F end, these are extremely versatile for small and mini assemblies of a number of different materials.

Our screws are made from Stainless Steel AISI-304 Grade to provide a strong corrosion resistant assembly for a long life to your product and are RoHS compliant.

Available in PAN Phillips and CSK Phillips Heads.

PAN Phillips PT Screws

 

The PAN head screws are very useful for higher clamping loads and are available from 1.2mm onward.

 

 

 

Now also available in Black Coated Finish

 

This finish is very useful in reducing light reflection from parts and providing an integrated finish to black coloured products and parts.

 

These screws have a permanent black colour with exceptional strength and elasticity that does not chip, peel, craze, or rub off and provides good resistance to wear and abrasion.

 

Usage Guide

• Always use trials to determine the optimal hole size and screw length. This will be dependent on depth of engagement, ease of driving required and material being tapped.
• Ensure trials  are made to determine the best tightening torque for your application. Use up to 80% of the values suggested by your trials.
