Abstract
A fastener for securing a drywall work piece to a metal substrate. The fastener includes an elongated flat body carrying a securing member and having a driving head disposed at a substantially right angle to the elongated flat body. The driving head defines a bore therein surrounded by a downwardly directed flange having a distal cutting edge which cuts the top paper laminate of the drywall allowing the head to countersink into the drywall without damaging the top paper laminate.
