ABSTRACT:
There is disclosed a universal or swivel joint having a ball member with an axis of rotation and a projection of substantially spherical shape centered on the axis, the surface of the projection containing a plurality of facets aligned with and uniformly and symmetrically positioned angularly around the axis of rotation, and a socket member having an axis of rotation and a receptacle centered on the axis which receptacle receives and mates with the ball member, the receptacle having an interior surface containing a plurality of facets aligned with and uniformly and symmetrically positioned angularly around the axis of rotation of the socket member, each of the facets of the receptacle mating with and being positioned in sliding engagement with a respective facet of the ball member. The universal ball and socket swivel joint may have a central opening therethrough symmetrically positioned about the axis of rotation of the ball member and the socket member into which another smaller ball and socket assembly substantially similar thereto may be coaxially aligned and located therein to form a dual independent coaxial universal swivel joint which may be connected to a coaxial drive fastener gun for driving a torque shear-bolt and nut assembly to angularly displace the coaxial drive axis of the fastener gun from the axis of rotation of the torque shear-bolt and nut.
