Built to accept a Z-type shank with a 0.990-inch shank diameter, it delivers a maximum torque output of 480 foot-pounds, making it suitable for heavy-duty bolting tasks where accurate torque control is critical. The 1 3\/4-inch open-end head size and a center-of-fastener-to-retaining-pin measurement of 5.75 inches allow access to fasteners in a range of tight or offset installation scenarios. Mechanics, pipefitters, and millwrights who require controlled torque on large fasteners will find this head fits into a standard torque wrench drive system without modification.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is suited for use in commercial and industrial environments where large-diameter fasteners require controlled tightening. Typical applications include flange bolting, heavy mechanical assembly, and equipment installation in HVAC, plumbing, and industrial maintenance settings. It is sold as a single unit and is intended for use with compatible Z-shank torque wrench handles. SAE sizing makes it appropriate for work on standard inch-measurement fasteners commonly found in North American mechanical systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 3\/4-inch open-end head for SAE fasteners\u003c\/li\u003e\n\u003cli\u003eMaximum torque rating of 480 foot-pounds for heavy-duty applications\u003c\/li\u003e\n\u003cli\u003eZ-type shank with 0.990-inch shank diameter for secure drive connection\u003c\/li\u003e\n\u003cli\u003eCenter of fastener to retaining pin measures 5.75 inches for offset access\u003c\/li\u003e\n\u003cli\u003eCompact profile at 0.87 inches height for use in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Z-shank torque wrench handles that accept a 0.990-inch shank diameter.

Ensure the wrench handle is fully de-energized or relieved of any preload before attaching or removing the head. Verify that the shank seats fully and the retaining pin engages securely prior to applying torque. Follow applicable industry torque standards and job-site specifications when tightening fasteners.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 1 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Open End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 0.990 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Z\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 480 foot-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter of Fastener to Retaining Pin\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.41 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: SAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILLIAMS COMFORT PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QZO56A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51345971511602,"sku":"QZO56A","price":212.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310544650.jpg?v=1782067961","url":"https:\/\/voomisupply.com\/products\/williams-comfort-products-qzo56a-torque-wrench-head","provider":"Voomi Supply","version":"1.0","type":"link"}
