Williams Comfort Products QXO46A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QXO46A is an open-end torque wrench head designed for precise fastener tightening in demanding trade applications. Built to a 1 7/16-inch opening, it accepts a 0.735-inch X-type shank and delivers a maximum torque of 240 ft-lb. The center-of-fastener to retaining pin distance measures 4.5 inches, providing the clearance needed for accurate torque transfer. This head is suited for use with compatible torque wrench handles in mechanical, HVAC, and industrial service work where controlled fastener torque is required. Licensed tradespeople and experienced service technicians are the primary users.

The QXO46A is used in situations where a standard box or socket-style head cannot access a fastener due to space constraints or fastener orientation. The open-end design allows side-loading onto a fastener, making it practical for tight or partially obstructed work areas. It is sized for SAE fastener applications and is sold individually. Typical applications include mechanical system assembly, equipment installation, and service work in HVAC, industrial maintenance, and related trades.
