Every mechanic knows that having a reliable set of tools can make your life easier when working on truck wheels in the workshop. The STEELMAN PRO 79332 10-Piece 1-Inch Drive Truck Wheel Servicing Socket Set contains a wide variety of heavy-duty sockets used to work on and service wheels on large trucks and tractor trailers. Set includes the following standard (SAE) and metric sizes 13/16-inch square Budd, 7/8-inch, 15/16-inch, 1-inch, 1-1/16-inch thin wall deep, 1-1/8-inch thin wall deep, 1-3/16-inch, 1-1/4-inch thin wall deep, 1-1/2-inch deep, and 33mm deep sockets. Made from drop forged and heat treated chromoly steel, these sockets feature a ball detent recess on the 1-inch drive end to help them hold 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 sockets each feature 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, these can handle tough use in any professional shop / garage or home workshop. When not in use the sockets can be stored in the included metal storage box.
