Williams JHW1215MSC 15 Mm 12-point Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1215MSC is a 15 MM combination wrench built for professional use in trade environments where fastener integrity matters. It features a SUPERCOMBO open end and a SUPERTORQUE box end, both engineered to place wrenching force on flat fastener surfaces rather than corners. This design reduces the risk of rounding or deforming hex fastener points under high torque. The 12-point box opening accommodates a wide range of common hex fasteners. At 0.346 pounds and approximately 9 inches in length, it is a manageable, single-piece hand tool suitable for HVAC, plumbing, and mechanical service work.

This wrench is suited for residential and commercial service applications where metric fasteners are encountered on equipment, piping, fittings, and structural components. The SUPERCOMBO open end includes grooves that redirect wrenching force away from fastener corners, providing a meaningful advantage over conventional open-end designs in tight or repetitive-use scenarios. Licensed trades including HVAC technicians, plumbers, and pipefitters will find this wrench effective for routine maintenance and equipment installation tasks requiring metric fastener engagement.

Key Features

• SUPERTORQUE 12-point box end applies force to flat fastener surfaces, not corners, reducing fastener deformation under high torque
• SUPERCOMBO open end uses engineered grooves to redirect wrenching force away from fastener corners
• Compatible with all common 6-point hex fasteners, offering flexibility over standard box end wrenches
• High-polish chrome finish for corrosion resistance and ease of cleaning
• Meets ANSI B107.6 and SAE AS 954 federal specifications
• Lightweight at 0.346 pounds for reduced hand fatigue during extended use

Compatibility

Designed for use on all common 6-point hex fasteners requiring a 15 MM opening, suitable for metric fastener applications across HVAC, plumbing, and mechanical service work.

Installation Notes
