Williams Comfort Products JHWBWM-2124 Box End Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBWM-2124 is a 12-point box end wrench built for professional trade use in mechanical, HVAC, plumbing, and general service applications. It features a SUPERTORQUE box opening design that contacts the flat surfaces of hex fasteners rather than the corners, allowing higher torque application without rounding or deforming fastener points. The wrench spans a 21 x 24 MM dual opening and measures 13.25 inches overall length. The box ends are offset at 10 degrees to provide clearance in confined work areas. Size markings are stamped on the handle ends for quick identification during service work.

This wrench is suited for residential and commercial mechanical service work where metric fasteners are common. The dual-size 21 MM and 24 MM openings cover a range of hardware found on HVAC equipment, pipe flanges, equipment panels, and general mechanical assemblies. The 10-degree offset box end is particularly useful when working in tight quarters around ductwork, pipe runs, or equipment enclosures where a straight wrench cannot seat properly. It is sold individually and is appropriate for use by licensed trades and skilled service technicians.

Key Features

• SUPERTORQUE box opening contacts flat fastener surfaces, not corners, reducing the risk of rounding hex points under high torque

• Dual 21 MM and 24 MM openings in a single tool
• 12-point box design allows engagement at multiple angles
• Size markings on handle ends for fast identification

Compatibility

Designed for use with standard metric hex fasteners requiring 21 MM or 24 MM wrench engagement, typical in commercial and residential mechanical equipment service.

Installation Notes

This wrench is used by licensed HVAC technicians, plumbers, electricians, and general mechanical service trades. Always ensure the wrench is fully seated on the fastener before applying torque to avoid slippage. De-energize or shut down any equipment before performing fastener work on live systems. Inspect the wrench for cracks or wear before each use and replace if damage is found.
