Product Details
The TEKTON 9-piece 3/8 inch drive crowfoot wrench set includes sizes 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, and 3/4 inches, along with a black inch-size wrench key. The wrenches feature a lean design optimized for access and strength by using steel only where necessary and eliminating excess material. They are made from 4140 chromium-molybdenum steel, heat-treated to 50-54 HRC, and have a satin finish achieved by abrasive blasting. Each wrench is electroless nickel plated, providing a uniform, corrosion-resistant surface. The wrench sizes are laser engraved on the top surface with large, permanent, easy-to-read markings. This set exceeds the ASME B1074.100-2020 strength requirements for minimum proof torque, ensuring high performance and durability.
