Product instruction:

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 a tap. 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.
