21mm Extra Thin Wall 1/2" Drive

21mm Extra Thin Wall 1/2" Drive   Every mechanic knows the importance of having a reliable set of tools, and the STEELMAN PRO 79405 1/2-Inch Drive x 21mm Deep Well X-Thin Wall 6-Point Single Metric Impact Socket was made to make your life easier when working on cars, trucks, and other heavy-duty equipment. Constructed of chromoly (CrMo) steel for strength and lasting durability, this impact socket has been hardened to resist drive end round out for a lifetime of dependable use. Fitting easily onto any 1/2-inch drive impact extension, torque stick, adapter or impact wrench's anvil, this socket's recessed edges provide the most accurate fit possible with its' 6-point design gripping fasteners by the sides and not the edges resulting in reduced slippage and rounding/fastener damage. In addition, the extra-thin-walled design allows this socket to reach fasteners where the minimal side clearance makes them impossible to reach with standard, thicker walled sockets.
