The PROTO J1238HASD is a combination wrench built for professional trade use in maintenance, mechanical, and industrial applications. It features a 1-3/16 inch head size with a 15-degree offset on the box end, allowing clearance in tight or obstructed fastener locations. The wrench is machined from steel with a satin finish that reduces glare and resists corrosion. At 15-7/8 inches overall length and weighing 1.63 pounds, it delivers the leverage needed for heavy fastener work. The design is tether capable, making it suitable for work-at-height environments where dropped-tool protocols are in effect. It meets ASME B107.100 standards and carries a lifetime warranty.
This wrench is used across mechanical, HVAC, plumbing, and industrial maintenance trades wherever 1-3/16 inch fasteners are encountered. The 15-degree offset box end is particularly useful when working in recessed or confined spaces where a flat wrench profile cannot clear surrounding structure. The straight handle and 6-point box end provide solid grip and reduce the risk of fastener rounding under high torque. The tether-capable design addresses safety requirements on elevated work platforms, scaffolding, and rooftop mechanical units.
Designed as a standard combination wrench for 1-3/16 inch fasteners in mechanical, HVAC, plumbing, and industrial maintenance applications.
This wrench is intended for use by qualified tradespeople following applicable workplace safety standards. Always ensure the fastener and wrench head are fully engaged before applying torque. When working at height, attach the tether point to an approved anchor to comply with dropped-object prevention requirements. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found.
