Apex 81631 Stubby Combination Wrench 12 Point 13/16 in

Product Description

The APEX 81631 is a stubby 12-point combination wrench sized at 13/16 inch, designed for use in confined spaces where a standard-length wrench will not fit. Built from alloy steel with a full polish finish, it resists rust and corrosion under regular shop and field conditions. The off-corner loading design on both the box and open ends grips fasteners more securely, reduces rounding, and delivers up to 25 percent more torque than standard corner-contact designs. The size is stamped directly into the beam for permanent identification. The box end is offset 15 degrees to improve access in tight fastener locations.

This wrench is well suited for mechanical, HVAC, plumbing, and electrical trade work where fastener access is limited by surrounding hardware, panels, or structures. The stubby pattern length makes it practical in equipment bays, junction boxes, and mechanical rooms. It is sold individually and fits standard 13/16-inch fasteners commonly found across residential and light commercial equipment.

Installation Notes

This wrench is used by licensed tradespeople and experienced technicians across mechanical service disciplines. Always ensure the wrench is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Inspect the tool for cracks or deformation before each use and do not use a cheater bar or extension on a stubby wrench.
