3/8 Inch Drive Crowfoot Wrench Set with Keys, 21-Piece (5/16 - 3/4 in., 8 - 19 mm)

• Lean Design – We optimized our crowfoot wrenches for access and strength by using steel only where it matters and eliminating the excess • Exceeds Performance Standards – Tekton 3/8 inch drive crowfoot wrenches greatly exceed the ASME B1074.100-2020 strength requirements for minimum proof torque • Satin Finish – Our crowfoot wrenches are made from 4140 chromium-molybdenum steel that's heat-treated to 50-54 HRC and abrasive-blasted for a finely textured finish • Electroless Nickel Plating – Our plating process ensures a uniform, corrosion-resistant finish across the entire surface of the crowfoot wrench • Clear Markings – The wrench sizes are laser engraved on the top surface of each tool with a large, permanent marking that’s easy to read
Tekton crowfoot wrenches are part of our system of access wrenches, designed as ultimate access tools that can fit into tight spaces where others can't. These wrenches are finished with an electroless nickel plating process that offers several key advantages, including complete corrosion protection on interior surfaces and a better fit in the jaws, as the plating material doesn't accumulate at the tips as with conventional chrome plating. Additionally, this process has a lower environmental impact since it doesn't require the use and disposal of chromium. We make the wrenches entirely in the USA with USA-sourced materials. The steps of machining, broaching, engraving, vibration polishing, abrasive blasting, and plating all take place locally at Tekton's Grand Rapids, Michigan manufacturing facility.
