Socket Drive Size Adapter 1/4" F x 3/8 M

Pin Free hex ball designed to provide flexibility when working in tight restricted areas. Wobble design smoothly transfers the torque of a high power pneumatic tool around obstructions that cannot accommodate a standard socket. Hex joint provides increased reliability and service life over pin mounted universal joints. Locking wobble works by simply pulling out the male end for full range of motion (wobble) or keep it retracted for use as a straight adapter or extension. Will not bind up like universal joints. Quickly convert between 1/4", 3/8" drives without changing hand tools. Super tough impact grade wobbles handle the high torque of pneumatic tools without failing.
