Williams Comfort Products QJXBM19A Torque Wrench Head 19MM

Product Description

The WILLIAMS COMFORT PRODUCTS QJXBM19A is a 19 MM metric torque wrench head designed for precision fastening applications in trade and mechanical service work. The head features a 12-point configuration and a J-type shank measuring 0.425 inches, providing a secure drive interface with compatible torque wrench handles. Maximum rated torque is 60 ft-lb, making this head suitable for a range of controlled-torque fastening tasks where accurate load application is required. Weighing 0.15 pounds, the QJXBM19A is a compact, single-piece component sold individually. It is intended for use by mechanical technicians, HVAC service professionals, plumbers, and other tradespeople who require metric torque wrench accessories.

This torque wrench head is used in service scenarios where a 19 MM metric fastener must be tightened to a specified torque value rather than by feel. Typical applications include equipment installation, component assembly, and maintenance procedures on mechanical systems where over-tightening or under-tightening a fastener can cause system failure or leaks. The 12-point socket geometry allows engagement in tighter spaces where swing arc is limited, and the J-shank design indexes securely into the drive end of a compatible torque wrench body.

Installation Notes

This torque wrench head should be installed onto a compatible torque wrench handle before use. Always verify the torque wrench handle and head connection are fully seated before applying load. Do not exceed the 60 ft-lb maximum torque rating of this head. Always power down or isolate the system being serviced before applying torque to any fastener on live equipment.
