Williams Comfort Products QXO42A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QXO42A is a 1 5/16 inch open-end torque wrench head designed for precision fastening work in trade and industrial applications. It accepts an X-type shank with a 0.735 inch shank diameter and delivers a maximum torque rating of 240 ft-lb, making it suitable for high-load fastening tasks. The center-of-fastener to retaining pin distance measures 4.5 inches. Licensed tradespeople working in HVAC, plumbing, or mechanical contracting will find this head useful wherever a standard torque wrench drive cannot access a fastener directly.

This torque wrench head is suited for residential and commercial trade applications that require controlled torque on SAE fasteners. Its open-end design allows access to fasteners in confined spaces or where socket engagement is not possible. The X-type shank interface mates with compatible torque wrench handles to deliver accurate torque transfer without slippage. It is sold individually and is appropriate for service, maintenance, and installation tasks across mechanical trades.
