Product Details
The 13-piece 3/8 inch drive crowfoot wrench kit includes wrenches sized 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1 inch, along with a 13-tool black crowfoot wrench rack. These wrenches are made from 4140 chromium-molybdenum steel that is heat-treated to 50-54 HRC and feature a satin finish achieved by abrasive blasting. They are electroless nickel plated to provide a uniform, corrosion-resistant surface. The wrench sizes are laser engraved on the top surface with large, permanent markings for easy visibility. The design is optimized for access and strength by using steel only where necessary, eliminating excess material. This tool set greatly exceeds the ASME B1074.100-2020 performance standards for minimum proof torque.
