Product Description

The WILLIAMS COMFORT PRODUCTS QXO58A is an open-end torque wrench head designed for precision fastening applications where controlled torque output is required. Sized at 1 13/16 inches with an X-type shank measuring 0.735 inches, this head mounts to compatible torque wrenches and delivers a maximum torque rating of 240 ft-lb. The center of fastener to retaining pin measurement is 4.5 inches. At 0.38 pounds, it is a compact, single-piece tool component suited for use by mechanics and service technicians working in tight or precise fastening environments.
