Abstract

See full text

A polygonal bit is frictionally retained in a mating socket opening of a drive socket by the provision of recesses in the flat surfaces of the bit, the formation of each recess creating a raised ridge of material displaced from the recess and projecting from the flat surface around the perimeter of the recess for frictional engagement with the corresponding drive surface of the drive socket. Recesses may be formed in flat surfaces on opposite sides of the bit, with one or two recesses being formed in each such surface. Various shapes of recess are disclosed.
