Williams Comfort Products QZO46ADP Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO46ADP is a dual-pin open-end torque wrench head designed for high-torque fastening applications in demanding trade environments. Built with a Z dual-pin shank type, this head delivers a maximum torque capacity of 480 foot-pounds, making it suitable for heavy-duty assembly, maintenance, and fastener installation tasks. At 1 7/16 inches, the open-end design accommodates specific fastener sizes where a closed socket cannot be used. The unit weighs 1.81 pounds and is sized at 8 inches in length overall, providing a manageable profile for technicians working in tight or confined spaces. This tool is sold individually and is intended for use with compatible torque wrench drives in professional settings.

This torque wrench head is used in industrial, mechanical, and heavy trade applications where precise, repeatable torque is required on SAE-sized fasteners. The open-end configuration is particularly useful when access is limited or when working on fasteners that cannot be fully engaged by a standard socket. The 5 3/4-inch center-of-fastener to retaining-pin measurement is a key dimensional reference for confirming fit within a torque wrench system setup. HVAC, mechanical, and industrial technicians will find this head applicable in equipment installation and service scenarios requiring controlled torque output.

Installation Notes

This torque wrench head should be installed and operated by qualified technicians familiar with torque tool systems and safe fastener practices.
