Product Name : Pan Philips Self Tapping Screws
Product Code : AHC-15
A Pan Phillip self-tapping screw is a Pan Headed 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).
