1-1/2 Inch Service Wrench

• 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 50–53 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
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. They complement our other access wrenches, including crowfoot, flare nut crowfoot, and angle head wrenches. The drive square at the end of the handle adds versatility when paired with a ratchet or a torque wrench, and has detent grooves on all four sides. Wrench sizes with a 3/8 inch drive square include 3/4–1-1/2 inch and 19–38 mm. Wrench sizes with a 1/2 inch drive square include 1-9/16–2-5/8 inch and 41–50 mm. The center-to-center distance between the drive square and the hex opening is engraved on the handle for quick reference when using the service wrench as a torque adapter. Our service wrench jaws are much leaner than our standard combination wrenches, with 33% to 46% less jaw thickness (depending on the size). The tip of each jaw has a 10-degree lead-in taper that helps align the wrench with the hex flats when visibility is limited. We make our service wrenches from 4140 chromium molybdenum steel and harden them to 50–53 HRC. The wrenches are abrasive-blasted to create a finely textured satin finish and then plated with corrosion-resistant nickel that is easy to wipe clean. 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.
