Built to SAE specification, this head accepts a Z-type shank with a 0.990-inch shank diameter and delivers a maximum torque rating of 480 ft-lb. At 2.24 pounds, it is a solid, purpose-built tool head suited for use by mechanics, millwrights, and trade technicians working on heavy-duty assemblies. The 1 11\/16-inch open-end size targets larger fasteners common in industrial and mechanical service work.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is suited for professional applications requiring controlled torque delivery on large SAE fasteners. The open-end design allows access in confined or offset positions where a standard socket cannot engage. The center-of-fastener to retaining-pin dimension of 5 3\/4 inches provides the offset geometry needed for specific fastener placements. Typical use cases include equipment assembly, mechanical system service, and maintenance work on heavy machinery or HVAC and plumbing infrastructure installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 11\/16-inch open-end head size for large SAE fasteners\u003c\/li\u003e\n\u003cli\u003eMaximum torque rating of 480 ft-lb for heavy-duty applications\u003c\/li\u003e\n\u003cli\u003eZ-type shank with 0.990-inch shank diameter for secure drive connection\u003c\/li\u003e\n\u003cli\u003eCenter of fastener to retaining pin: 5 3\/4 inches for offset access\u003c\/li\u003e\n\u003cli\u003eSAE specification for compatibility with standard inch-measurement fasteners\u003c\/li\u003e\n\u003cli\u003eCompact profile at 0.79 inches height for use in tight clearances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Z-type torque wrench drives accepting a 0.990-inch shank.
