Abstract
A universal joint for power drive tools and the like. The universal assembly includes a means for connection to a tool and a means for engaging the nut or a head of a fastening member, such as a bolt. Articulation of the universal is accomplished by means of a quadrified ball in a square socket. The head of the ball retains its spherical form, and the base of the socket is spherical in shape to accommodate the ball head. The four sides of the quadrified ball do not intersect thereby retaining the spherical configuration of the ball at the corners. A unique ball spring preloads the socket. The resulting combination is ideally suited for power drive tools wherein the forces generated are high, and the rotation is rapid.
