Williams Comfort Products QZX50A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZX50A is a torque wrench head designed for high-load fastening applications in trade and industrial environments. This head features a 15-degree offset box end with a 12-point configuration, giving technicians access to fasteners in tight or angled spaces where a straight head cannot seat properly. The 1 9/16-inch opening size and 0.990-inch Z-type shank connect to compatible torque wrench handles for controlled, repeatable tightening. Maximum rated torque is 480 foot-pounds, making it appropriate for heavy-duty mechanical and structural fastener work. Licensed tradespeople and journeyman mechanics installing large-scale equipment are the primary users of this tool.

This torque wrench head is suited for commercial and industrial mechanical service work where precise torque application is required on larger fasteners. The 15-degree offset box end allows the technician to work at an angle when bolt access is restricted by surrounding components or structure. The 12-point socket geometry provides multiple engagement positions, reducing repositioning time in confined locations. HVAC riggers, pipefitters, millwrights, and heavy equipment mechanics will find this head applicable in equipment installation and structural assembly tasks requiring controlled torque output up to 480 foot-pounds.
