C.S. Unitec EX203-030UB Double Open Ended Wrenches, Copper Beryllium, 3/8" x 7/16

Features: 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 ...

Features: Optimized for Engagement, Access, and Strength – Our deep, 6-point design maximizes your contact with fittings and prevents slipping Reinforced Jaw Strength – We reinforced our wrenches with material where it matters most to avoid high stress concentrations and prevent the jaws from spreading 15-Degree Offset Increases Access Angles – The jaw opening is offset 15 degrees from the center of the wrench so that it can be flipped over to gain additional access angles Electroless Nickel Plating for Corrosion Resistance – The electroless nickel plating finish is easy to wipe clean, ...

Features: 180° Flex Heads-The flex head sweeps smoothly through 180 degrees without any set positions. This allows the wrench to operate at any angle and navigate around obstructions in its swing path. 12-Point Box Ends-Fits multiple types of fasteners, including 6-point, 12-point, and square. 1/4, 9/32, 5/16, and 11/32 inch and 6, 7, 8, and 9 mm wrenches have a 60-tooth ratcheting mechanism. All other sizes have a 72-tooth ratcheting mechanism. Clear Markings-Tekton flex head ratcheting wrenches are permanently marked in two ways: a high-visibility laser marking and a stamped ...

The 55 series of open-end wrenches have a matte chrome finish and have two open ends to fit SAE (fractional inch) fasteners. Each end fits a different size fastener for twice the coverage and are set at a 15° angle to the shank for easy access in tight areas.

The 142AS series of wrenches from Beta Tools have one open end (15° angle) and a 12-point box end (15° offset) with a toggle-reversing ratchet mechanism. Both ends fit the same size SAE (inch) fasteners. The high-polish, chrome-plated finish looks great and wipes clean easily after use. The Beta logo and series of number are stamped in the center of the handle, and the fractional size is stamped at each end of the handle.
