Williams Comfort Products QZO50ADP Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO50ADP is an open-end torque wrench head designed for high-torque fastening applications in professional trade and industrial settings. Sized at 1 9/16 inches, this head features a Z dual-pin shank type and a dual-pin retention design. It delivers a maximum torque capacity of 480 foot-pounds, making it suitable for heavy-duty bolted connections where precise torque application is required. Licensed mechanics, millwrights, and industrial technicians rely on this type of tooling where standard socket access is limited and controlled torque output is critical.

This torque wrench head is used in applications requiring open-end access to fasteners in confined or restricted spaces. The SAE sizing standard and dual-pin shank interface make it compatible with corresponding torque wrench drives used in mechanical, structural, and equipment assembly environments. The center of fastener to retaining pin dimension measures 5 3/4 inches, which determines reach and clearance in the work area. It is sold individually as a single unit.

Key Features

• Open-end head type for access to fasteners where a closed socket cannot seat

• Maximum torque rating of 480 foot-pounds for heavy-duty fastening
• SAE sizing standard at 1 9/16 inches
• Center of fastener to retaining pin distance of 5 3/4 inches

Compatibility

Designed for use with torque wrench bodies that accept a Z dual-pin shank interface. Consult your torque wrench drive documentation to confirm pin spacing and shank compatibility before installation.

Installation Notes

Installation and use of this torque wrench head should be performed by qualified mechanics or technicians familiar with controlled torque procedures. Inspect the dual-pin shank and retaining pin engagement before applying load. Do not exceed the rated maximum torque of 480 foot-pounds, as overloading can damage the head or the fastener assembly. Follow applicable industry torque standards and equipment manufacturer specifications for the joint being assembled.
