Williams JHW1246TSB 12-pt Box End Wrench 1 7/16 in Straight

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1246TSB is a 12-point straight box end wrench with a 1 7/16 inch opening, built for trade professionals who need reliable torque access in confined spaces. The straight box head design keeps the wrench low-profile, making it practical when clearance is limited around fasteners. A detent on the wrench shaft aligns the locking button with the handle hole, so the tool stays positioned correctly during use. This wrench is sold as a single unit and suits mechanical, HVAC, and plumbing applications where larger hex fasteners are common.

This wrench is designed for use with or without an optional handle, giving the technician flexibility on the job. Without the handle attached, the tubular body lets the user run down nuts quickly. Once the handle is added, it provides full turning leverage for final tightening or for reaching fasteners in otherwise inaccessible locations. Both SAE and corresponding metric fastener sizes are marked on the wrench, reducing the need for a separate reference during service work. It is well suited for residential and light commercial mechanical service environments.

Installation Notes

This wrench is typically used by licensed HVAC technicians, plumbers, and mechanical service professionals. Before beginning any fastener work on pressurized systems, shut off all relevant gas, water, or electrical supply per applicable service codes. Use the handle-free configuration to run down fasteners quickly, then attach the optional handle for final torque. Inspect the detent and locking button before each use to confirm the handle is fully seated and locked.
