Abstract
A hand tool is used to drive a fastener about an axis, and includes a handle with an axially extending bore for receiving frictionally a fastener engaging member. The engaging member has an axially extending inner surrounding surface, and an inner peripheral wall which extends radially and inwardly to define a mounting hole communicating with the inner surrounding surface. A deformable member is inserted into the mounting hole, and has a protrusion extending inwardly of the inner surrounding surface when the engaging member is received in the handle. A bit, which includes two screwdriver tip ends and a shaft, is brought to be inserted into and is coupled to rotate with the engaging member axially such that the protrusion frictionally engages the shaft radially so as to hinder removal of the bit from the engaging member axially.
