Self Tapping And Drilling and Wood Screws

Item Code: B4B23

Product Details:

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 HEX 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.

• 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.

• 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.

• 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.

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.

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

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.
