Abstract

See full text

An improved screwdriver in which a replaceable bit is removably secured to a mandrel by the bit being axially slidable in an axial socket in the end of the mandrel. The bit is movable from a position coaxially aligned with the socket to a position out of alignment therefrom, to assist in the engagement and driving of misaligned screws. A resilient split-ring which serves to retain the bit in the socket is carried by and replaceable with the bit. With each new bit a new split-ring is also provided.
