Built with a 1.5-inch open-end head and a Z-type shank measuring 0.990 inches, this tool accepts standard torque wrench drives and delivers a maximum torque capacity of 480 ft lb. The center of fastener to retaining pin measures 5.75 inches, providing the clearance needed for confined or offset fastening scenarios. Licensed mechanics, millwrights, and industrial service technicians reach for this head when standard sockets cannot access a fastener due to space or geometry constraints.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is suited for heavy mechanical assemblies, industrial equipment maintenance, and structural fastening tasks that demand precise, high-torque application. The open-end head configuration allows engagement on fasteners where a closed socket cannot fit, making it a practical choice for pipe flanges, large machinery mounts, and similar applications. Sold individually, it pairs with compatible torque wrenches using a Z-type shank interface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.5-inch open-end head for large fastener engagement\u003c\/li\u003e\n\u003cli\u003eZ-type shank with 0.990-inch shank size for secure torque wrench coupling\u003c\/li\u003e\n\u003cli\u003eMaximum torque rating of 480 ft lb for heavy-duty fastening\u003c\/li\u003e\n\u003cli\u003e5.75-inch center of fastener to retaining pin for offset and confined access\u003c\/li\u003e\n\u003cli\u003eSAE sizing for use in standard inch-measurement fastening systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with torque wrenches that accept a Z-type shank interface.
