Product Description
18-8 Stainless Steel M3.5 M4.2 Phillips Truss Wafer Head Self Drilling Screws
A selftapping 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 selftapping 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 selftapping one can (within
reasonable limits of substrate hardness and depth). For softer substrates such as wood or soft plastics,
the selftapping 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.
