ABSTRACT:
The invention relates to polygonal flank sockets, or drives, for correspondingly shaped fasteners which impart the torque turning load thereto, and more particularly relates to sockets and socket drives adapted to accommodate nut type fasteners that are complements thereof, of improved construction to more effectively sustain nut turning loads. The present arrangement insures surface-to-surface flat engaging contact between the splines and flanks of the nut fasteners for any purpose requiring torque or turning loads. In the present invention, straight surface-to-surface contact for load transmitting action is assured, whereby greater torque loads can be transmitted with the wrench socket embodying the teachings of the present invention.
