Built to accept a Z-type shank with a 0.990-inch shank diameter, this head delivers a maximum torque rating of 480 ft-lb, making it suitable for heavy-duty bolted connections where controlled torque is critical. The 1 7\/16-inch open-end jaw fits standard SAE fasteners of that size. With a center-of-fastener to retaining pin measurement of 5.75 inches, it provides the reach needed in confined or offset installation scenarios. Mechanical contractors, pipefitters, and industrial maintenance technicians will find this head useful wherever high-torque SAE fastening is required.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is intended for use with compatible torque wrench handles that accept a Z-type shank. It is well suited for mechanical, plumbing, and industrial applications involving large SAE fasteners, flange bolts, and structural connections. The open-end head style allows engagement on fasteners in locations where a box or socket end cannot seat fully. Typical use cases include equipment installation, large valve assembly, and structural bolted joint assembly in commercial and industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 7\/16-inch open-end jaw fits standard SAE fasteners of that size\u003c\/li\u003e\n\u003cli\u003eMaximum torque capacity of 480 ft-lb for heavy-duty fastening applications\u003c\/li\u003e\n\u003cli\u003eZ-type shank with 0.990-inch shank diameter for compatible torque wrench handle fitment\u003c\/li\u003e\n\u003cli\u003eCenter-of-fastener to retaining pin distance of 5.75 inches for offset reach\u003c\/li\u003e\n\u003cli\u003eOpen-end head style allows fastener engagement in restricted access areas\u003c\/li\u003e\n\u003cli\u003eCompact profile at 7.56 inches length and 0.87 inches height for tight clearances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with torque wrench handles that accept a Z-type shank with a 0.990-inch shank diameter.
