Williams Comfort Products JHWBWM-1011 Box End Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBWM-1011 is a 12-point box end wrench engineered for professional fastener work in tight, high-torque applications. It features a SUPERTORQUE box opening that applies wrenching force to the flat surfaces behind fastener points rather than the corners, reducing the risk of rounding or deforming hex fasteners under load. The wrench spans a 10 x 11 MM opening and measures 7 31/32 inches in overall length. A 10-degree offset on the box end provides clearance in confined spaces. Size markings are stamped on the handle ends for quick identification in the field. This wrench is designed for use by mechanics, plumbers, HVAC technicians, and other trade professionals who require reliable torque application on metric fasteners.

This wrench suits residential and light commercial maintenance, service, and installation work where metric fasteners are common. The dual-end design gives the technician two sizes in a single tool, making it practical for multi-fastener jobs without reaching for a second wrench. The 10-degree offset box end is especially useful in areas where a straight wrench cannot seat flush on the fastener. Meets ANSI B107.9M federal specification requirements, confirming dimensional and performance standards appropriate for professional use.

Key Features

• SUPERTORQUE box opening applies force to flat fastener surfaces, not corners, reducing deformation under load
• 12-point design for increased engagement positions around the fastener
• 10-degree offset box end provides clearance in restricted spaces
• Dual-size 10 x 11 MM opening eliminates the need for two separate wrenches
• Size markings on handle ends allow fast identification
• Meets ANSI B107.9M federal specification

Compatibility

Designed as a standard metric box end wrench suitable for use with 10 MM and 11 MM hex fasteners in mechanical, plumbing, HVAC, and general trade service applications.

Installation Notes

This tool is installed or used by any licensed trade professional working with metric hex fasteners. Ensure the wrench is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Inspect the wrench for cracks or deformation before each use. Do not extend the handle with a pipe or secondary tool, as this can exceed safe torque limits and damage the wrench or fastener.
