Williams Comfort Products QZOM55ADP Torque Wrench Head 55MM

Product Description

The WILLIAMS COMFORT PRODUCTS QZOM55ADP is a 55 MM open-end torque wrench head designed for high-torque fastening applications requiring precise rotational force control. It features a dual-pin Z shank interface that locks securely into compatible torque wrenches, preventing slippage during operation. Rated to a maximum torque of 480 foot-pounds, this head is built for heavy-duty use where standard sockets are impractical. Weighing 7.2 pounds and measuring 8 inches in length by 1 inch in height, it is a substantial tool suited for professional mechanical and industrial trades.

This torque wrench head is used in applications requiring precise torque delivery to large fasteners, particularly in industrial maintenance, heavy equipment service, and mechanical assembly environments. The open-end design allows access to fasteners in configurations where a closed or box-end head cannot engage. Technicians working on large machinery, flange connections, or structural bolted assemblies will find the 55 MM sizing appropriate for metric fastener specifications common in commercial and industrial settings.

Key Features

• 55 MM open-end head fits large metric fasteners
• Dual-pin Z shank provides positive engagement with compatible torque wrenches
• Maximum torque rating of 480 foot-pounds for heavy-duty fastening
• Open-end design allows use in confined or obstructed fastener locations
• Sold individually as a single unit

Compatibility

Designed for use with torque wrenches that accept a Z dual-pin shank interface. Verify shank compatibility with your existing torque wrench before installation.

Installation Notes

Installation should be performed by qualified mechanical or industrial technicians familiar with torque tooling and fastener specifications. Ensure the dual-pin shank is fully seated and locked into the torque wrench before applying load. Do not exceed the maximum torque rating of 480 foot-pounds. Follow applicable industry standards and equipment manufacturer specifications when torquing critical fasteners.
