Abstract
An auxiliary head with a peripheral wrench surface is secured on a body member of a type having a threaded shank, a head, and lateral projecting means adjacent the bottom of the head which extend out beyond the outer dimension of the threads on the shank. Such auxiliary head has an axial opening which is larger than the threaded shank so as to receive the latter but is dimensioned at least in some portions thereof relative to the projecting dimension of the lateral projecting means such that securement of the two parts is accomplished by forcing the auxiliary head up against the bottom of the head of the body member onto the lateral projecting means in a press fit or in a broached connection.
