Proto J1024A Box End Wrench 3/4 X 13/16 in 12 Pt Double End

Product Description

The PROTO J1024A is a double-end box wrench designed for professional tradespeople who need reliable torque transfer in tight spaces. Built from steel with a polished finish, this wrench features 12-point box ends on both sides, sized at 3/4 inches and 13/16 inches. The 12-point configuration allows for 30-degree arc swings, giving technicians more repositioning options in confined fastener locations. At 0.748 pounds and 12.2 inches in length, it delivers solid leverage without unnecessary bulk. It meets ASME B107.10 standards and carries a lifetime warranty, making it a long-term addition to any professional tool kit.

This wrench is well suited for HVAC, plumbing, electrical, and general mechanical work where 3/4-inch and 13/16-inch fasteners appear regularly. Common applications include equipment installations, ductwork connections, pipe fittings, panel work, and mechanical assemblies. The double-end design reduces the number of individual wrenches needed on the job, and the polished steel construction resists surface wear during repeated use in field and shop environments.

Installation Notes

This tool is used by licensed tradespeople and general mechanics across multiple disciplines. Always ensure the correct end is fully seated on the fastener before applying torque to prevent rounding. Inspect the wrench for cracks or deformation before each use. No power source or lockout procedure is required for the wrench itself, but always follow applicable jobsite safety and equipment lockout/tagout procedures when servicing live systems.
