Williams Comfort Products JHWBWM-1213 Box End Wrench 12x13mm

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBWM-1213 is a 12-point box end wrench designed for professional fastener work in mechanical, plumbing, and HVAC service environments. It features a SUPERTORQUE box opening that applies wrenching force to the flat surfaces behind the fastener points rather than the corners, reducing the risk of rounding or deforming hex fasteners under high torque. The 10-degree offset box end provides clearance in tight spaces where a standard wrench cannot seat properly. Opening sizes are 12 MM and 13 MM, and the wrench meets ANSI B107.9M specifications.

This wrench is suited for trade professionals who work with metric fasteners in confined or awkward installations. Typical applications include equipment mounting, pipe flange work, panel hardware, and service calls where metric fasteners are common. The dual-size opening reduces the number of tools needed on a job. At 0.25 pounds, it is light enough to carry in a standard tool pouch without adding significant weight.

Key Features

• SUPERTORQUE box opening contacts flat fastener surfaces, not corners, for higher torque without fastener damage
• 12-point configuration for easier engagement in limited-swing situations
• 10-degree offset box end for clearance in tight or recessed work areas
• Dual metric openings: 12 MM and 13 MM
• Size markings on handle ends for fast identification in a tool bag
• Meets ANSI B107.9M federal specification

Compatibility

Designed as an OEM-style hand tool for use with 12 MM and 13 MM metric hex fasteners across general mechanical, HVAC, plumbing, and electrical service applications.

Installation Notes

This wrench is a hand tool used by licensed tradespeople across HVAC, plumbing, electrical, and mechanical service disciplines. No power source is required. Ensure the correct opening size is seated fully on the fastener before applying torque to avoid slippage. Do not use extension bars or pipes to increase leverage beyond the wrench handle design.
