Williams Comfort Products QJRXSM11A Torque Wrench Head 11MM

Product Description

The WILLIAMS COMFORT PRODUCTS QJRXSM11A is an 11 MM flare nut torque wrench head designed for precision fastening in mechanical and HVAC service applications. Built with a 6-point contact geometry, it delivers consistent torque transfer up to 42 ft-lb without rounding fastener flats. The J-type shank measures 0.425 inches and interfaces with compatible torque wrench handles. This head is sold individually and is intended for use by licensed HVAC technicians, plumbers, and mechanical contractors who require accurate, repeatable torque on metric flare fittings.

This torque wrench head is suited for residential and light commercial service work where metric flare nut fasteners are present, such as refrigerant line connections, gas line fittings, and hydronic piping joints. The flare nut profile wraps around the fitting hex to reduce the risk of damage during tightening. It is a practical addition to a field technician's torque wrench set when working on metric-spec equipment or imported systems requiring controlled fastener loads.
