Abstract

A tool for rotatably driving a fastening member includes a hollow tubular shank closed at one end by a handle fixed thereto and having coupled to the other end thereof in communication therewith a socket for receiving an associated rotatable fastening member. A helical compression spring is disposed coaxially within the shank, having the inner end thereof embedded in a body of adhesive material and having the outer end thereof fixed to the keeper of a magnet disposed for magnetic engagement with a fastening member received in the socket. In assembly, the adhesive material is inserted in the shank in a fluid state, the inner end of the spring is immersed in the fluid, and the adhesive is then cured to a solid state.
