Williams Comfort Products QJOM13A Torque Wrench Head 13MM

Product Description

The WILLIAMS COMFORT PRODUCTS QJOM13A is a 13 MM open-end torque wrench head designed for use with J-shank torque wrenches in metric fastener applications. The head accepts a J-type shank measuring 0.425 inches and delivers a maximum torque output of 41 ft-lb, making it suitable for precision fastening tasks where accurate torque is required. Sold individually, this wrench head is intended for use by mechanics, technicians, and trade professionals who need a dedicated metric open-end head for their existing J-shank torque wrench drive system.

This torque wrench head is used in service and installation scenarios where metric fasteners must be torqued to specification and a standard socket cannot be used due to space or fastener geometry. Open-end heads are common in HVAC, mechanical, and plumbing service work where hex-head fittings and bolts in tight spaces require an open-ended engagement rather than a full socket enclosure.
