TEKTON 37 mm Service Wrench | WSE14437 | Made in USA

Part of a System of Access Wrenches Tekton service wrenches are short-handled, open-end access wrenches with a 15-degree angled head on one side and a drive square on the other, and they complement our other access wrenches | Drive Square in Handle The drive square can be used with a ratchet or other drive tools to increase access or leverage and apply specific torque; four detent grooves secure the connection | Thin Jaw for More Access Our service wrench jaws are much leaner than our standard combination wrenches, with 33% to 46% less jaw thickness (depending on the size), providing better access in tight spaces and on thin fittings | 4140 Steel, Satin Nickel Finish We make our service wrenches from 4140 chromium molybdenum steel and harden them to 5053 HRC, then abrasive-blast them to create a finely textured satin finish and plate them with corrosion-resistant nickel | Manufactured in Michigan Our service 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
