Williams Comfort Products QYXM21A Torque Wrench Head 21MM

Product Description

The WILLIAMS COMFORT PRODUCTS QYXM21A is a 21 MM torque wrench head designed for precision fastening applications in mechanical and trade service work. This head features a 12-point configuration and a Y-type shank measuring 0.560 inches, allowing it to seat securely in compatible torque wrench handles. Rated to a maximum torque of 160 ft lb, the QYXM21A is built for high-load fastening tasks where accurate torque delivery is critical. It is sold individually and is suited for professional mechanics, industrial technicians, and trade professionals who require metric tooling with reliable torque transfer.

The QYXM21A is used in residential and commercial mechanical service environments where 21 MM metric fasteners require controlled torque application. Typical install scenarios include engine and drivetrain service, HVAC equipment assembly, heavy mechanical equipment maintenance, and any application involving metric hardware in the 21 MM range. The 12-point head geometry provides more contact points than a 6-point alternative, reducing fastener rounding risk in tight or repetitive-use situations.

Key Features

• 21 MM metric sizing for broad compatibility with standard metric fasteners
• 12-point head design for increased contact and reduced fastener damage risk
• Y-type shank at 0.560 inches for secure torque wrench handle engagement
• Maximum torque rating of 160 ft lb for high-load fastening applications
• Compact profile: 0.7 inches length, 3.9 inches width, 1.1 inches height
• Lightweight at 0.21 pounds for reduced hand fatigue during extended use

Compatibility

Designed as a replacement or supplemental torque wrench head for use with compatible Y-type shank torque wrench handles accepting a 0.560 inch shank. Verify shank interface specifications of the handle before installation.

Installation Notes

Installation of this torque wrench head should be performed by a qualified mechanic or trade professional familiar with torque tooling systems. Ensure the shank is fully seated and locked into the wrench handle before applying load. Do not exceed the 160 ft lb maximum torque rating to avoid tool damage or fastener failure. Inspect the head for wear or deformation before each use.
