Williams Comfort Products QJO52A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QJO52A is an open-end torque wrench head designed for precise fastener tightening in trade and mechanical service applications. Built to SAE specification, it accepts a J-type shank measuring 0.425 inches and delivers a maximum torque output of 60 foot-pounds. The 1 5/8-inch open-end head provides access to fasteners in confined spaces where a standard torque wrench body cannot reach directly. This head is suited for HVAC, plumbing, and mechanical technicians who require controlled torque application on larger fasteners during equipment installation or maintenance.

This torque wrench head is used in residential and light commercial service work where fastener torque must be controlled and verified. Typical applications include equipment mounting, refrigerant line fittings, and mechanical assembly tasks that call for a 1 5/8-inch open-end engagement. The J-type shank connects to compatible torque wrench bodies, extending reach and angle access in tight installation environments.
