Gearwrench 86131 Box End Wrench 3/8 Inch 12 Point Double End

Product Description

The GEARWRENCH 86131 is a double-end box wrench built for professional hand-tool use in mechanical, HVAC, plumbing, and general trade applications. Manufactured from chromium-vanadium steel with a polished finish, this wrench delivers corrosion resistance and lasting durability under daily shop or field use. The 12-point box end accepts 3/8-inch fasteners and features a ratcheting mechanism, allowing the technician to drive fasteners without removing and repositioning the tool on each stroke. The 0-degree head angle keeps the profile flat and low-clearance. Head thickness measures 0.27 inches on one side and 0.29 inches on the other. Meets ASME B107.6 and ANSI specifications. Backed by a limited lifetime warranty.

The 86131 is suited for residential and commercial mechanical work where access to 3/8-inch fasteners is required. The ratcheting 12-point box end is particularly useful in confined spaces where swing arc is limited, such as equipment panels, compressor mounts, and piping connections. The double-end configuration provides versatility from a single tool. Licensed mechanics, HVAC technicians, plumbers, and electricians all find ratcheting box wrenches essential for routine service and installation tasks.

Installation Notes

No power shutoff is required for hand-tool use, but always de-energize equipment and follow relevant safety lockout-tagout procedures before servicing any mechanical system. Inspect the wrench before use for cracks or wear. Do not apply extension bars or additional leverage to box end wrenches beyond their intended use, as this can damage the tool or fastener.
