This head features a dual-pin Z shank interface and an open-end design sized at 1.375 inches. It handles a maximum torque output of 480 foot-pounds, making it well suited for heavy-duty mechanical and industrial assembly work. The center-of-fastener to retaining-pin measurement is 5.75 inches, providing the clearance and leverage geometry required for consistent, repeatable torque application. Technicians working in mechanical, HVAC equipment assembly, or industrial maintenance will find this head compatible with standard CDI torque wrench drive systems.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is appropriate for use in commercial and industrial settings where large fasteners require controlled torque application. The open-end configuration allows access to fasteners in confined or offset positions where a standard socket cannot seat fully. It is commonly used by mechanical technicians and equipment service professionals working on heavy machinery, large HVAC units, and structural mechanical assemblies that demand accurate high-torque fastening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOpen-end head design for access to fasteners in tight or offset locations\u003c\/li\u003e\n\u003cli\u003eDual-pin Z shank for secure, positive engagement with compatible torque wrench handles\u003c\/li\u003e\n\u003cli\u003eMaximum torque capacity of 480 foot-pounds for heavy-duty applications\u003c\/li\u003e\n\u003cli\u003e1.375-inch head size for large fastener compatibility\u003c\/li\u003e\n\u003cli\u003e5.75-inch center-of-fastener to retaining-pin dimension for precise leverage geometry\u003c\/li\u003e\n\u003cli\u003eSAE sizing for use in standard domestic fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CDI torque wrench systems accepting a Z dual-pin shank interface.
