Williams Comfort Products QZO54ADP Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO54ADP is an open-end torque wrench head engineered for high-torque fastening applications where precise rotational force is required. Sized at 1 11/16 inches with a Z Dual Pin shank design, this head delivers a maximum torque rating of 480 ft-lb, making it suitable for heavy-duty industrial and mechanical assembly work. The dual-pin drive interface provides positive engagement and reduces slippage under load. The center-of-fastener to retaining-pin dimension measures 5 3/4 inches, a critical reference for clearance planning in confined or tight-access installations. Licensed tradespeople and professional mechanics rely on this type of head for torque-critical fastener applications where standard sockets or combination wrenches cannot provide verified torque values.

This torque wrench head is designed for use in demanding mechanical environments where SAE fastener torque specifications must be met consistently. It is suited for heavy equipment maintenance, large-diameter pipe flanges, structural bolting, and industrial assembly operations. The open-end head configuration allows access to fasteners in restricted spaces where a closed-end or socket-style tool cannot engage. It is paired with compatible torque wrench handles that accept a Z Dual Pin drive shank.

Key Features

• 1 11/16 inch open-end head size for SAE fasteners
• Z Dual Pin shank type for secure drive connection
• Maximum torque capacity of 480 ft-lb
• Center-of-fastener to retaining-pin distance of 5 3/4 inches for clearance planning
• Open-end head design allows access in restricted-clearance fastener locations

Compatibility

Designed for use with torque wrench handles that accept a Z Dual Pin drive shank. Specific handle compatibility should be confirmed against the torque wrench manufacturer documentation before use.

Installation Notes

Installation and use of this torque wrench head should be performed by qualified mechanical tradespeople familiar with torque specifications and fastener standards. Ensure the mating torque wrench handle is rated at or above the 480 ft-lb maximum torque of this head before applying load. Inspect the dual-pin shank and retaining-pin engagement for wear or damage prior to each use. Follow applicable industry torque standards and equipment manufacturer specifications for the fastener application.
