Williams Comfort Products QZO64ADP Torque Wrench Head 2 in

Product Description

The WILLIAMS COMFORT PRODUCTS QZO64ADP is a 2-inch open-end torque wrench head designed for high-load fastening applications. It features a dual-pin shank configuration that locks securely onto compatible torque wrench drives, delivering controlled torque output up to 480 foot-pounds. The head is built for industrial and heavy-duty mechanical work where precise, repeatable torque is required on large fasteners. Technicians working in commercial HVAC, plumbing, pipefitting, and general mechanical trades will find this head suited to demanding bolted joint applications that require accurate torque control.

This torque wrench head is intended for use with Z dual-pin drive torque wrenches in SAE applications. The 2-inch open-end design fits large hex fasteners commonly found in heavy mechanical assemblies, flanged connections, and structural bolted joints. With a center-of-fastener to retaining pin measurement of 5.75 inches, it is suited for installations where clearance around the fastener is limited and a standard socket cannot be used. Sold individually as a single unit.

Installation Notes

Install and removal of torque wrench heads should be performed by qualified mechanical or trade technicians familiar with torque tool systems. Verify the wrench drive and head shank type match before use, and confirm the tool is within its calibrated range before applying load. Do not exceed the rated maximum torque of 480 foot-pounds. Inspect the dual-pin interface for wear or damage prior to each use to ensure accurate torque transfer.
