Williams Comfort Products JHW1219MSC Combination Wrench 19MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1219MSC is a 19 MM, 12-point combination wrench built for professional hand-tool applications requiring both open-end and box-end access. The open end uses a SUPERCOMBO profile with machined grooves that redirect wrenching force away from fastener corners, reducing the risk of rounding under load. The box end uses a SUPERTORQUE design that contacts the flat surfaces of the hex rather than the corners, allowing higher torque application without deforming fastener points. The wrench carries a high-polish chrome finish and conforms to ANSI B107.6 and SAE AS 954 specifications.

This wrench is suited for use on all standard 6-point hex fasteners across a wide range of trade applications, including HVAC equipment assembly, refrigeration piping, plumbing fixture work, and electrical panel installation. The 12-point box end provides additional positioning flexibility in tight spaces where swing arc is limited. At 0.666 pounds and approximately 11 inches in length, it is sized for one-hand use in confined equipment access areas.

Key Features

• SUPERCOMBO open end directs force away from fastener corners to reduce rounding
• SUPERTORQUE 12-point box end contacts flat hex surfaces, not corners, enabling higher torque without fastener damage
• Compatible with all common 6-point hex fasteners, offering an advantage over standard 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 19 MM hex fasteners; suitable as a general-purpose combination wrench across HVAC, plumbing, electrical, and mechanical service applications.

Installation Notes

This wrench is used by licensed HVAC technicians, plumbers, electricians, and general mechanical trades. Ensure the correct size is selected before applying torque to avoid fastener damage. When working near energized components or pressurized lines, de-energize electrical circuits and isolate system pressure before using hand tools on fasteners. Do not use extension bars or cheater pipes on combination wrenches not rated for extended-leverage torque.
