Williams Comfort Products JHWBWM-1113 Box End Wrench 11x13mm

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBWM-1113 is a 12-point box end wrench designed for professional fastener work in demanding trade environments. It features an 11 mm by 13 mm double-ended opening and an overall length of 8.625 inches. The SUPERTORQUE box opening geometry applies wrenching force to the flat surfaces of hex fasteners rather than the corners, reducing the risk of rounding or deforming fastener points under high torque. The 10-degree offset box end provides clearance in confined spaces where a straight wrench cannot seat properly. Size markings are stamped on the handle ends for quick identification in a tool pouch or on a crowded work surface.

This wrench is suited for licensed HVAC technicians, plumbers, gas fitters, and mechanical contractors working on equipment that uses metric fasteners. Typical applications include servicing unit panels, compressor hardware, valve bodies, and equipment mounting hardware where metric hex fasteners are standard. The double-ended configuration covers two common metric sizes in a single tool, reducing the number of wrenches needed on the job.

Key Features

• SUPERTORQUE 12-point box opening contacts flat fastener surfaces, not corners, for higher torque without deformation
• 10-degree offset box end provides knuckle clearance and access in tight spaces
• Double-ended design covers 11 mm and 13 mm fasteners in one wrench
• Overall length of 8.625 inches provides adequate leverage for most service applications

• Meets ANSI B107.9M dimensional and performance standards

Compatibility

Designed as a professional-grade metric box end wrench for use with standard 11 mm and 13 mm hex fasteners commonly found on HVAC equipment, plumbing components, and mechanical assemblies.

Installation Notes

This wrench is a hand tool requiring no installation. Always confirm the correct metric opening size seats fully on the fastener before applying torque to avoid slippage. Power down or isolate the equipment being serviced before loosening fasteners on live systems. Follow applicable OSHA hand-tool safety guidelines and manufacturer service procedures for the equipment being worked on.
