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.
