Built to an SAE specification with a 1 3\/16 inch open-end head, this wrench head accommodates a 0.990 inch Z-type shank and delivers a maximum torque rating of 433 foot-pounds. The center of fastener to retaining pin measurement is 5 3\/4 inches, providing consistent geometry for controlled torque application. This is a precision hand tool intended for use by experienced mechanics, HVAC technicians, plumbers, and other tradespeople who require accurate torque output on large fasteners.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is suited for heavy-duty fastening tasks in residential and commercial mechanical installations. It is appropriate for applications where standard combination wrenches cannot achieve the required torque level, such as flange connections, large mechanical fittings, and structural fastener assemblies. Its open-end head design allows access to fasteners in confined or partially obstructed spaces common in mechanical rooms and equipment installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 3\/16 inch open-end head for SAE fasteners\u003c\/li\u003e\n\u003cli\u003eMaximum torque capacity of 433 foot-pounds\u003c\/li\u003e\n\u003cli\u003e0.990 inch Z-type shank for compatible torque wrench drives\u003c\/li\u003e\n\u003cli\u003eCenter of fastener to retaining pin distance of 5 3\/4 inches\u003c\/li\u003e\n\u003cli\u003eSold individually as a single head unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with compatible Z-shank torque wrench drives accepting a 0.990 inch shank diameter.
