ABSTRACT:
A driver has a tip that enables it to engage each one of a conventional hexagonal-head fastener and a conventional lobed-head fastener. The tip includes alternating flutes and crests. The crests are substantially flat to engage straight walls of a hexagonal-head. The flutes engage the lobed head of the fastener. A socket-type driver engages each type of conventional fastener. A fastener and a pair of socket-type fasteners have alternating flutes, which can be engaged by a conventional lobed-head driver, and crests or sidewall surfaces, which can be engaged by a conventional hexagonal-head driver.
