Williams JHW7039B 12-point Offset Box End Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW7039B is a 12-point offset box end wrench designed for professional trade use in mechanical, plumbing, HVAC, and industrial service applications. It features a 1-1/4 by 1-5/16 inch dual-size opening and a 10-degree offset box end that provides clearance in confined or recessed work areas. The SUPERTORQUE box opening geometry applies wrenching force to the flat surfaces of hex fasteners rather than the corners, allowing higher torque to be applied without rounding or deforming fastener points. Sizes are stamped on the handle ends for quick identification in the field. This wrench meets ANSI B107.6 federal specifications.

The JHW7039B is suited for mechanical and trade professionals working on equipment assemblies, pipe fittings, structural fasteners, and HVAC equipment where two close but distinct fastener sizes appear in the same work area. The offset box end design is particularly useful when working around obstructions or in areas where a straight wrench cannot be positioned at a useful angle. It is sold individually as a single unit.

Installation Notes
