It accepts an X-type shank with a 0.735 inch shank diameter, allowing it to mate with compatible torque wrench handles for controlled tightening. The head delivers a maximum torque output of 193 ft-lb, making it suitable for heavy-duty fastener work on mechanical systems. The center-of-fastener to retaining-pin measurement is 4.5 inches. Licensed HVAC technicians, plumbers, and industrial mechanics rely on this type of head for consistent, repeatable torque application where standard fixed wrenches fall short.\u003c\/p\u003e\n\u003cp\u003eThis torque wrench head is used in residential and commercial mechanical service work where precise fastener torque is required. Typical applications include tightening flange bolts, fitting connections, and mechanical assembly tasks encountered in HVAC, plumbing, and general mechanical contracting. The open-end head design provides access to fasteners in locations where a box or socket head cannot seat properly. It is sold as an individual head and pairs with a compatible X-shank torque wrench handle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8 inch open-end head for direct fastener engagement without a socket\u003c\/li\u003e\n  \u003cli\u003eMaximum torque rating of 193 ft-lb for heavy-duty fastening\u003c\/li\u003e\n  \u003cli\u003eX-type shank with 0.735 inch diameter for secure handle connection\u003c\/li\u003e\n  \u003cli\u003eCenter-of-fastener to retaining-pin distance of 4.5 inches\u003c\/li\u003e\n  \u003cli\u003eSAE sizing for use with standard inch-measurement fasteners\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 0.5 inches height for access in tight clearances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with torque wrench handles that accept an X-type shank.
