Williams JHW1212MSC Combination Wrench 12 Mm 12-point

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1212MSC is a 12 MM combination wrench featuring a 12-point box end and a SUPERCOMBO open end, designed for professional trade use in mechanical, HVAC, plumbing, and electrical service work. The open end uses specially designed grooves to direct wrenching force away from fastener corners, reducing the risk of rounding. The SUPERTORQUE box end contacts the flat surfaces behind hex points rather than the corners themselves, allowing higher torque application without deforming fasteners. The high-polish chrome finish resists corrosion and simplifies cleanup in demanding field conditions.

This wrench is suited for residential and commercial service environments where technicians work with metric fasteners on equipment, panels, and mechanical assemblies. The 12-point box end provides more engagement positions per revolution, making it practical in tight spaces with limited swing arc. It is sold individually and is appropriate for licensed HVAC technicians, plumbers, electricians, and other trade professionals who need a reliable metric hand tool for daily service work.

Key Features

• SUPERCOMBO open end with grooves that redirect force away from fastener corners
• SUPERTORQUE 12-point box end contacts flat surfaces behind hex points, not corners, for higher torque capacity
• Compatible with all common 6-point hex fasteners, offering an advantage over conventional box end wrenches
• High-polish chrome finish for corrosion resistance and easy cleaning
• Meets ANSI B107.6 and SAE AS 954 federal specifications

Compatibility

Designed for use on standard metric hex fasteners with a 12 MM opening. Suitable for general mechanical service across HVAC, plumbing, electrical, and industrial maintenance applications.

Installation Notes

This wrench is a hand tool requiring no installation. Before servicing equipment, power down electrical systems and shut off gas or water supplies as applicable to the task. Use the box end for initial loosening and final torquing where higher torque is needed, and the open end for faster spinning in accessible areas. Follow applicable codes such as NEC, IFGC, or IPC when working on trade systems.
