1" Drive x 7/8" 6-Point Impact Socket

Every mechanic knows that having a reliable set of tools can make your life easier when working on heavy-duty vehicles and equipment. The STEELMAN PRO 79336 is ideal for use in performing maintenance, repairs and service on large trucks and tractor trailers, farming equipment and tractors, oilfield and construction equipment, and mass transit vehicles. Made from drop forged and heat treated chromoly steel, this socket features a ball detent recess on the 1-inch drive end to help hold it securely onto ratchets, air wrenches, adapters, and extensions. The 6-point design grips the sides of fasteners and not the corners, reducing wear and the chance of rounding the fastener. The socket features a rust and corrosion resistant black phosphate protective coating with laser etched size callouts and markings. Rated to withstand up to 150% of ASME torque requirements for impact tools, this socket can handle tough use in any professional shop / garage, home workshop, or on the work site.
