Product Details
The kit includes a set of crowfoot wrenches optimized for access and strength by using steel only where necessary and eliminating excess material. These 3/8 inch drive crowfoot wrenches meet and exceed the ASME B1074.100-2020 strength requirements for minimum proof torque. Made from 4140 chromium-molybdenum steel, the wrenches are heat-treated to 50-54 HRC and abrasive-blasted to provide a finely textured satin finish. They are coated with electroless nickel plating to ensure a uniform, corrosion-resistant surface. The wrench sizes are laser engraved clearly on the top surface for easy readability. The package offers two options: a 9-piece set with sizes 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, and 3/4 inch; and a 12-piece set with sizes 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19 mm. Additionally, the kit includes a black wrench key and a red wrench key.
