Abstract

This invention relates to the field of driving heads of fasteners, for example screws, and a driver for these fasteners (for example a screwdriver). More particularly, the invention relates to miniature screws (hereinafter referred to as fasteners) that are small and have thin heads. According to the present invention, there is provided a fastener comprising a driving head and a shank, wherein the driving head includes a recess having a top and bottom portion for receiving a bit of a driver, said recess further comprising an abutment extending from the bottom portion of the recess and said abutment runs along the periphery of the recess. Thus, relative to conventional fastener/driver systems, the fastener can be inserted and removed by the driver more quickly and with a reduced possibility of slippage, stripping, or other hazardous, undesired positional divergence of the driver from the fastener.
