Williams Comfort Products JHWSFH-1816W Striking Face Box Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHWSFH-1816W is a 12-point striking face box end wrench with a 2.75-inch opening, built for heavy industrial fastener work. This tool is designed to be struck with a hammer on its anvil area, delivering the impact force needed to break loose frozen or heavily torqued fasteners or to seat and set fasteners under load. The anvil is proportioned to match the 2.75-inch opening size, and the straight handle geometry resists springing during use. Special heat treating throughout the body provides durability suited for sustained, high-demand service environments. At 9.92 pounds, it is a substantial tool built for rigorous use.

This wrench is used in heavy industrial maintenance, construction, and overhaul applications where standard hand torque is insufficient. It is a common choice for millwrights, pipefitters, ironworkers, and maintenance mechanics working on large fasteners found in structural assemblies, heavy machinery, flanges, and industrial piping systems. The straight handle allows clearance for fastener rotation while keeping the striking anvil accessible. It fits into job sites where air or hydraulic impact tools are impractical or unavailable, and a hammer-driven approach is required.

Key Features

• 12-point box end configuration engages fastener flats for positive grip during hammer strikes
• 2.75-inch opening suits large industrial fasteners in structural and mechanical applications
• Anvil sized proportionally to opening for safe, efficient hammer blows
• Special heat treatment process maximizes durability and extends service life under repeated impact
• Straight handle design resists springing and allows fastener rotation with minimal obstruction
• Engineered for sustained rigorous industrial use, not light-duty or occasional service

Compatibility

Designed as an OEM-style striking face box end wrench for use on large industrial fasteners with a 2.75-inch across-flats dimension in heavy mechanical, structural, and piping applications.

Installation Notes

This tool is installed and used by millwrights, pipefitters, and industrial mechanics. Always use a ball-peen or engineer's hammer rated for striking tool use — do not use a standard claw hammer on the anvil face. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found. Wear appropriate eye and hand protection when striking, as impact work can produce flying debris.
