It accepts a Z-type shank with a 0.990-inch shank diameter, allowing it to mount to compatible torque wrenches for controlled, accurate tightening. The head delivers a maximum torque rating of 480 ft-lb, making it suitable for large fasteners found in mechanical, HVAC, and industrial piping work. The center-of-fastener to retaining pin distance measures 5.75 inches. Licensed trades professionals and industrial mechanics are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis torque wrench head is used in applications requiring precise high-torque output on large fasteners, particularly in mechanical rooms, industrial facilities, and commercial HVAC or plumbing installations. Its open-end design provides access to fasteners in locations where a closed or box-end head cannot be seated. The SAE sizing makes it appropriate for standard inch-measurement fastener stock commonly found in domestic mechanical equipment and structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5-inch open-end head for large SAE fasteners\u003c\/li\u003e\n  \u003cli\u003eMaximum torque capacity of 480 ft-lb\u003c\/li\u003e\n  \u003cli\u003eZ-type shank with 0.990-inch shank diameter for secure drive attachment\u003c\/li\u003e\n  \u003cli\u003eCenter-of-fastener to retaining pin distance of 5.75 inches\u003c\/li\u003e\n  \u003cli\u003eSold individually (each) for single-head purchase flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or supplementary open-end torque wrench head for use with Z-shank torque wrench handles accepting a 0.990-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis torque wrench head is installed and used by licensed mechanics, pipefitters, and HVAC technicians working on large mechanical assemblies. Ensure the Z-type shank is fully seated and the retaining pin is properly engaged before applying torque load. Never exceed the rated maximum torque of 480 ft-lb, as overloading can damage the head or the fastener.
