The crowfoot head measures 1-3\/32 inches in diameter and 1\/4 inch thick, allowing access to fasteners in confined spaces where conventional wrenches cannot reach. The chrome-plated finish provides corrosion resistance for extended tool life in shop and field environments. At 1-23\/32 inches overall length and 0.13 pounds, this wrench is sized for precision work on metric fasteners and meets ASME B107.21 and federal specification GGG-C-1507b. It is suited for automotive, mechanical, and industrial maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis crowfoot wrench is used wherever torque must be applied to a fastener in a recessed or obstructed location. Common applications include HVAC compressor fittings, plumbing connections, engine accessory mounting bolts, and hydraulic line fittings. The open end design accepts hex fasteners from the side, which is useful when there is no top clearance for a socket. Metric sizing makes this tool appropriate for equipment manufactured to metric standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/32 inch head diameter for metric fastener engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch head thickness for work in tight clearances\u003c\/li\u003e\n  \u003cli\u003e1-23\/32 inch overall length for compact reach\u003c\/li\u003e\n  \u003cli\u003eChrome-plated finish resists corrosion in shop and field conditions\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B107.21 and federal specification GGG-C-1507b\u003c\/li\u003e\n  \u003cli\u003eLimited Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4-inch drive torque wrenches and extension bars as an OEM-style crowfoot attachment for metric fastener applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this crowfoot wrench onto a calibrated torque wrench or breaker bar before engaging the fastener. When using a crowfoot at an angle offset from the torque wrench drive axis, apply a correction factor to achieve accurate torque output per standard mechanical procedures. Ensure the fastener head is fully seated in the open end jaws before applying torque to prevent rounding. Always wear appropriate hand protection when working in confined mechanical spaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-3\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-23\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Chrome-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B107.21, GGG-C-1507b\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Limited Lifetime Warranty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\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: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J4917MCF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542723035442,"sku":"J4917MCF","price":57.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e33fa0c08af37e82ca9f0893f59111af.jpg?v=1785905398","url":"https:\/\/voomisupply.com\/products\/proto-j4917mcf-open-end-crowfoot-wrench-1-3-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
