The 9\/16-inch open-end head accepts a J-type shank measuring 0.425 inches and delivers a maximum torque capacity of 58 foot-pounds. The center-of-fastener to retaining-pin distance measures 2.5 inches, providing consistent reach and positioning during use. This head is installed by mechanics, maintenance technicians, and trade professionals who require controlled torque output in tight or awkward fastening locations where a standard fixed-head torque wrench cannot reach effectively.\u003c\/p\u003e\n\u003cp\u003eThis torque wrench head is suited for industrial maintenance, HVAC equipment assembly, mechanical service work, and trade applications where SAE fastener sizes are standard. It is sold as a single unit and is intended for use with compatible J-shank torque wrench handles. The open-end design allows engagement with fasteners that are not accessible from above, making it practical in equipment panels, pipe connections, and machinery frames.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-inch open-end head for SAE fastener engagement\u003c\/li\u003e\n  \u003cli\u003eJ-type shank with 0.425-inch shank diameter for compatible handle fitment\u003c\/li\u003e\n  \u003cli\u003eMaximum torque rating of 58 foot-pounds\u003c\/li\u003e\n  \u003cli\u003eCenter-of-fastener to retaining-pin distance of 2.5 inches\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.17 pounds for reduced hand fatigue during extended use\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single interchangeable head\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with J-shank torque wrench handles that accept a 0.425-inch J-type shank.

Before attaching or removing torque wrench heads, ensure the torque wrench handle is set to its lowest torque value to relieve tension on the mechanism. Verify that the retaining pin is fully seated before applying torque to any fastener. Do not exceed the rated maximum torque of 58 foot-pounds to avoid damage to the head or fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 9\/16 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 Type\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 0.425 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 58 foot-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter of Fastener to Retaining Pin\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILLIAMS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QJO18A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS","offers":[{"title":"Default Title","offer_id":51344042754354,"sku":"QJO18A","price":80.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551950.jpg?v=1782027593","url":"https:\/\/voomisupply.com\/products\/williams-qjo18a-torque-wrench-head-9-16-inch-open-end","provider":"Voomi Supply","version":"1.0","type":"link"}
