It accepts a J-type shank measuring 0.425 inches and delivers a maximum torque output of 60 foot-pounds. The open-end head design allows access to fasteners in confined or partially obstructed locations where a full socket cannot seat. This type of torque wrench head is used by mechanics, industrial technicians, and field service professionals who require calibrated torque delivery with a non-socket interface. The center-of-fastener to retaining pin measurement is 2-1\/2 inches, which determines effective offset distance during use.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is suited for SAE fastener applications in mechanical, HVAC, and light industrial service work. It is intended for use wherever a 1-1\/4 inch open-end fitting is required and a standard socket-drive approach is not practical. The J-type shank connection allows it to pair with compatible J-shank torque wrench handles. It is sold as an individual head unit and is appropriate for both bench work and field installations requiring repeatable, controlled torque output.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch open-end head for SAE fasteners in tight or offset locations\u003c\/li\u003e\n\u003cli\u003eMaximum torque rating of 60 foot-pounds\u003c\/li\u003e\n\u003cli\u003eJ-type shank with 0.425 inch shank diameter for compatible handle attachment\u003c\/li\u003e\n\u003cli\u003eCenter-of-fastener to retaining pin distance of 2-1\/2 inches for accurate offset torque calculations\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 0.5 inches long, 3.4 inches wide, 2.5 inches tall\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.55 pounds for extended use without fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with J-shank torque wrench handles accepting a 0.425 inch J-type shank.

Confirm the shank connection is fully seated and the retaining pin is engaged before applying torque to any fastener. Do not exceed the rated maximum torque of 60 foot-pounds to avoid tool damage or fastener failure. When calculating applied torque with an offset head, account for the center-of-fastener to retaining pin distance per standard torque correction formulas.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 1-1\/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 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: 60 foot-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter of Fastener to Retaining Pin\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: SAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662459934123\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: QJO40A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51346841469234,"sku":"QJO40A","price":132.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310544280.jpg?v=1782092068","url":"https:\/\/voomisupply.com\/products\/williams-comfort-products-qjo40a-torque-wrench-head","provider":"Voomi Supply","version":"1.0","type":"link"}
