Williams Comfort Products QZO48ADP Torque Wrench Head Open End

Product Description

The WILLIAMS COMFORT PRODUCTS QZO48ADP is an open-end torque wrench head designed for high-torque fastening applications in professional trade and industrial settings. Built with a Z dual-pin shank configuration, this head delivers a maximum torque rating of 480 foot-pounds, making it suitable for heavy-duty bolted connections that require precise and repeatable torque application. The head measures 1.5 inches and features an open-end design for access in confined or obstructed fastener locations. It is sized for SAE fasteners and is typically used by millwrights, pipefitters, and maintenance technicians working on heavy mechanical assemblies.

This torque wrench head is intended for use in industrial maintenance, mechanical assembly, and heavy equipment service environments where high-torque fastener control is required. The open-end head type allows engagement of fasteners in tight clearance situations where a standard socket cannot seat. The center of fastener to retaining pin measurement is 5.75 inches, which determines offset reach during use. It is sold individually and is compatible with torque wrench drive systems accepting Z dual-pin shanks.
