Williams JHWSFH-1818W Box End Striking Face Wrench 3.5 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHWSFH-1818W is a 12-point box end striking face wrench with a 3.5-inch opening, built for industrial fastener work where standard wrenches fall short. This wrench is engineered to be struck with a hammer on its hardened anvil area, allowing technicians to break loose frozen or heavily torqued fasteners without damaging the tool. The anvil is proportioned to the opening size, and the steel receives special heat treatment for long service life. The straight handle design resists springing under impact load, keeping the wrench properly seated on the fastener during striking.

This striking face wrench is intended for use in heavy industrial environments where fasteners are seized, over-torqued, or otherwise resistant to standard hand-tool removal. It is suited for maintenance mechanics, millwrights, and industrial service technicians working on large structural bolts, flanges, or mechanical assemblies. Its 3.5-inch opening accommodates large-diameter fasteners common in heavy equipment, piping, and structural steel applications. This tool ships as a single unit and is intended for individual or set-based professional tool inventories.

Key Features

• Designed to be struck by a hammer on the anvil to break loose frozen or set fasteners

• Special heat treating process maximizes durability under repeated striking use
• Straight handle design resists springing and keeps the fastener engagement secure during impact
• 12-point box end configuration for multiple contact angles on hex fasteners

Compatibility

Designed as an OEM-style replacement and professional-grade striking face wrench for industrial maintenance and mechanical assembly applications requiring a 12-point box end with a 3.5-inch opening.

Installation Notes

This wrench is intended for use by qualified maintenance mechanics and industrial technicians. Always use an appropriate-weight dead-blow or striking hammer on the anvil face only — never strike the handle or box end body. Ensure the wrench is fully seated on the fastener before striking to avoid rounding. Follow applicable workplace safety and hand-tool standards when working in confined or high-torque environments.
