Williams Comfort Products JHW8817W Box End Wrench 12-point

Product Description

The WILLIAMS COMFORT PRODUCTS JHW8817W is a 12-point offset box end striking face wrench built for heavy industrial use. It features a 3.125-inch opening and a 16-inch overall length, giving technicians the reach and leverage needed to break loose frozen or heavily torqued fasteners. The anvil area is sized proportionally to the opening and receives hammer strikes directly, allowing controlled force application without damaging surrounding hardware. Special heat treating throughout the construction provides the durability required for sustained use in demanding shop and field environments.

This wrench is intended for industrial maintenance, mechanical, and millwright applications where fasteners have seized or require high break-out torque. The offset handle design positions the head close to the working surface, providing clearance in confined or restricted spaces. It is suited for use by maintenance mechanics, pipe fitters, and heavy equipment technicians working in industrial plants, refineries, and similar facilities where standard wrenches cannot generate enough force alone.

Installation Notes

This wrench is used by qualified mechanics and industrial maintenance technicians. Always ensure the wrench is fully seated on the fastener before striking the anvil. Use an appropriate dead-blow or ball-peen hammer rated for striking tool use. Inspect the anvil area for cracks or deformation before each use and remove from service if damage is found.
