Williams Comfort Products JHWBWM-1719 Box End Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBWM-1719 is a 12-point box end wrench designed for professional fastener work in trade and industrial applications. It features a SUPERTORQUE box opening that directs wrenching force onto the flat surfaces of hex fasteners rather than the corners, reducing the risk of rounding or deforming fastener points under high torque. The wrench opens at 17 MM on one end and 19 MM on the other, with an overall length of 11 9/32 inches. A 10-degree offset on the box end provides clearance in confined spaces. Weighing 0.53 pounds, it is built for regular field use by licensed tradespeople working in mechanical, HVAC, plumbing, and electrical environments.

This double-end box wrench is suited for residential and commercial service work where metric fasteners are common. The 17 MM and 19 MM openings cover a range of fastener sizes frequently encountered on HVAC equipment, pipe flanges, electrical enclosures, and mechanical assemblies. The offset box end makes it practical in areas where a straight wrench cannot achieve adequate swing arc. Size markings on the handle ends allow quick identification when working out of a tool bag or pouch.

Installation Notes

This wrench is a hand tool requiring no power source or special setup. Ensure the correct opening size is seated fully on the fastener before applying torque to avoid slippage. When working near energized equipment, follow applicable NFPA 70E or site-specific electrical safety protocols before use. Inspect the wrench periodically for cracks or deformation and remove from service if damage is found.
