Product Details
The 12-piece 3/8 inch drive crowfoot wrench set includes sizes 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19 mm, along with a red metric-size wrench key. These wrenches feature a lean design optimized for access and strength by using steel only where necessary and eliminating excess material. Made from 4140 chromium-molybdenum steel heat-treated to 50-54 HRC, they have a satin finish achieved by abrasive blasting. The electroless nickel plating provides a uniform, corrosion-resistant surface. Each wrench size is laser engraved on the top surface with large, permanent markings for easy readability. This set exceeds ASME B1074.100-2020 strength requirements for minimum proof torque, ensuring reliable performance and durability.
