Product Description

The WILLIAMS COMFORT PRODUCTS QZO34A is an open-end torque wrench head designed for precise, controlled fastening in demanding trade applications. Built to a 1-1/16 inch open-end size, it accepts a Z-type shank measuring 0.990 inches and delivers a maximum torque output of 321 ft-lb. The center-of-fastener to retaining pin distance is 5-3/4 inches. This head is intended for use by mechanics, pipefitters, and industrial maintenance technicians who require accurate torque application in confined or offset fastening scenarios.
