Williams JHW1211MSC 11 Mm 12-point Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1211MSC is an 11 MM combination wrench built for professional tradespeople who need reliable torque application on hex fasteners. It features a 12-point SUPERTORQUE box end and a SUPERCOMBO open end, both engineered to reduce fastener damage during high-torque applications. The box end contacts the flat surfaces of the fastener rather than the corners, minimizing rounding and deformation. A high-polish chrome finish resists corrosion and makes cleanup straightforward on the job. This wrench meets ANSI B107.6 and SAE AS 954 federal specifications.

This combination wrench is suited for use across HVAC, plumbing, electrical, and general mechanical service work where metric hex fasteners are encountered. The 11 MM opening fits common metric bolts and nuts found in equipment panels, pipe fittings, and mechanical assemblies. Its compact profile at approximately 7.1 inches in length makes it workable in tighter service spaces. The wrench is sold individually and is appropriate for both installation and routine maintenance tasks performed by licensed trade professionals.

Key Features

• SUPERTORQUE box end places wrenching force on fastener flat surfaces, not corners, reducing rounding risk
• SUPERCOMBO open end uses specially designed grooves to direct force away from fastener corners
• 12-point box opening allows engagement from more positions compared to standard 6-point box ends
• Compatible with all common 6-point hex fasteners for broad application flexibility
• High-polish chrome finish for corrosion resistance and easy cleaning
• Meets ANSI B107.6 and SAE AS 954 federal specifications

Compatibility

Designed for use with standard 11 MM hex fasteners commonly found in residential and commercial trade applications across HVAC, plumbing, and mechanical service work.

Installation Notes

This wrench is a hand tool used by licensed HVAC technicians, plumbers, electricians, and mechanical service professionals. Always de-energize equipment and shut off fluid supply lines before servicing fastened components. Use the box end for high-torque applications and the open end for faster spinning in accessible locations. Inspect the wrench for wear or damage before each use and replace if the jaws show signs of spreading or deformation.
