Williams JHWBWM-1315 Box End Wrench 12-pt 13x15mm

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBWM-1315 is a 12-point, double box end wrench designed for professional trade use in mechanical, HVAC, plumbing, and general service applications. It features openings of 13 MM and 15 MM with an overall length of 9.5 inches. The wrench is built around the SUPERTORQUE box opening design, which applies wrenching force to the flat surfaces of hex fasteners rather than the corners. This approach allows higher torque application without rounding or deforming fastener points, making it well suited for stubborn or precision-critical fasteners. A licensed technician or tradesperson performing equipment installation or maintenance will find this wrench practical for tight-clearance work.

This wrench fits residential and commercial service scenarios where metric fasteners are common, including HVAC equipment installation, hydronic system work, and general mechanical assembly. The 10-degree offset on the box end provides clearance in confined spaces, reducing the need to reposition or swap tools. Size markings on the handle ends allow quick identification when working from a tool bag or cart. It is sold as a single unit.

Key Features

• SUPERTORQUE box opening applies force to flat fastener surfaces, not corners, reducing rounding risk under high torque
• 12-point box end configuration for more engagement positions in restricted access areas
• Dual metric openings: 13 MM and 15 MM on a single wrench
• 10-degree offset box end for clearance in tight or recessed spaces
• Size markings stamped on handle ends for fast identification
• Meets ANSI B107.9M federal specification

Compatibility

Designed for use with standard metric hex fasteners requiring 13 MM or 15 MM box end engagement. Suitable for mechanical and trade service applications where ANSI B107.9M compliant hand tools are specified.

Installation Notes

This wrench is a hand tool requiring no power source or special code compliance beyond standard trade practice. Before servicing any equipment, follow proper lockout/tagout procedures and shut off all relevant energy sources. Inspect the wrench for cracks or deformation before applying high torque. Do not use extension bars or pipe extensions on this wrench to increase leverage beyond the tool's rated design.
