The Ultimate Access Tool Fits Where Others Can’t We optimized our crowfoot wrenches for access and strength by using steel only where it matters and eliminating the excess. ![]() Part of a System of Access Wrenches Tekton crowfoot wrenches are ultra-compact and designed to pair with a ratchet. They complement our other access wrenches, including flare nut crowfoot, service, and angle head wrenches. Crowfoot Wrench Comparison smaller desrip ![]() Performance Greatly Exceeds ASME Strength Requirements Data from: “Category 21, Type II, Class 1 Open End, 3/8 in. Square Drive.” ASME B107.100-2020. Sizes 5/16 in. and 11/32 in. do not have a standard ASME measurement. ![]() Two Levels of Retention ![]() ![]() Clear Size Markings The wrench sizes are laser engraved on the top surface of each wrench with a large, permanent marking that’s easy to read. ![]() ![]() Materials and Processes 4140 Steel, Satin Nickel Finish We make our 3/8 inch drive crowfoot wrenches from 4140 chromium-molybdenum steel and heat treat them to 50-53 HRC. The wrenches are abrasive-blasted to create a finely textured finish and then plated with nickel. ![]() Electroless Nickel Plating The electroless nickel plating finish is easy to wipe clean and highly resistant to corrosion. ![]() Uniform Coverage and Better Fit The electroless process applies a uniform coating to the entire tool surface. By comparison, electroplating, including conventional chrome plating, has varying thickness across the tool because the plating thickness depends on the electric current density at each point on the tool. The uniformity of an electroless coating has two major advantages: Complete corrosion protection on interior surfaces Better fit in the wrench jaws because plating material does not accumulate at the jaw tips ![]() Manufactured in Michigan Our crowfoot wrenches are made entirely in the USA with USA-sourced materials. Machining, broaching, engraving, vibration polishing, abrasive blasting, and plating take place at our Grand Rapids, Michigan, manufacturing facility. ![]() Organization Features Universal Organizer for Crowfoot Wrenches Slide the drive end of any 3/8 inch drive crowfoot wrench onto the organizer key. ![]() Ideal for On-the-Go The key keeps all your crowfoot wrenches organized, compact, and portable. ![]() Durable Single-Piece Polypropylene Construction ![]() |
