DIN 7971/ ISO 1481 Stainless Steel Slotted Pan Head Self Tapping Screw

 

A self-tapping screw is a screw that can tap its own hole as it is driven into it. For hard substrates such as metal or hard plastics, the self-tapping ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on atap. Thus, whereas a regular machine screw cannot tap its own hole in a metal substrate, a self-tapping one can (within reasonable limits of substrate hardness and depth). For softer substrates such as wood or soft plastics, the self-tapping ability can come simply from a tip that tapers to a gimlet point (in which no flute is needed). Like the tip of a nail or gimlet, such a point forms the hole by displacement of the surrounding material rather than any chip-forming drilling/cutting/evacuating action.

 

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 center drill. These screws combine a thrilling-like 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.

Self-tapping screws are used in a variety of applications ranging from DIY carpentry to surgery. Many dental implants and orthopedic bone screws are examples of self-tapping screws used in surgery.

 

Stainless steel because of its corrosion resistance, high temperature strength, oxidation resistance and low-temperature toughness of the skin is used. These characteristics describe them widely used in almost every industry.

 

Flat head fastener is designed to be flush with the surface when in use mating countersunk. Length measured from the top of the head. Self-drilling is very suitable for use with sheet metal.
