Williams Comfort Products QYRXSM21A Torque Wrench Head 21MM

Product Description

The WILLIAMS COMFORT PRODUCTS QYRXSM21A is a 21 MM flare nut torque wrench head designed for precise fastening in metric applications. It features a 6-point contact design and accepts a Y-type shank with a 0.560-inch shank size. The head handles a maximum torque of 113 ft-lb, making it suitable for high-load fastening tasks. This torque wrench head is used by mechanics, plumbers, HVAC technicians, and other trade professionals who require controlled torque on flare nut fittings. Its compact profile — 3.94 inches long, 1.38 inches wide, and 0.63 inches tall — allows work in tight spaces.

This wrench head is intended for use in trade and industrial settings where metric flare nut fittings require precise torque application. It is well suited for HVAC refrigerant line connections, plumbing installations, and mechanical assembly work where overtightening or undertightening a fitting can cause leaks or component damage. The flare nut design grips hex fittings on multiple faces, reducing the risk of rounding. Sold individually, it is a direct addition to compatible torque wrench drive systems using a Y-type shank interface.
