The crowfoot design allows technicians to reach fasteners in tight or obstructed spaces where a conventional box or open end wrench cannot seat. The chrome plating resists corrosion and makes cleanup straightforward in shop and field environments. At 3.4 inches in overall length and 0.55 pounds, it is a compact, lightweight addition to any professional tool kit. PROTO backs this wrench with a Limited Lifetime Warranty.\u003c\/p\u003e\n\u003cp\u003eThis crowfoot wrench is suited for automotive, HVAC, plumbing, and general mechanical applications where a standard wrench cannot access a recessed or crowded fastener. It is a common fit for service work on compressors, manifolds, valve bodies, and similar assemblies. The metric sizing makes it appropriate for equipment manufactured to metric fastener standards. Licensed mechanics, HVAC technicians, and plumbers will find it useful during equipment installation and preventive maintenance tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOpen end crowfoot design reaches fasteners in confined or obstructed spaces\u003c\/li\u003e\n  \u003cli\u003eChrome-plated finish provides corrosion resistance and ease of cleaning\u003c\/li\u003e\n  \u003cli\u003eMetric system of measurement for compatibility with metric fastener standards\u003c\/li\u003e\n  \u003cli\u003e3.4 inches overall length for compact reach in tight spaces\u003c\/li\u003e\n  \u003cli\u003eBacked by a Limited Lifetime Warranty from PROTO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-service crowfoot wrench for use with 3\/8-inch or 1\/2-inch square drive torque wrenches, ratchets, and extensions in metric applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is used by mechanics, HVAC technicians, and plumbers working on metric-fastened assemblies. Always ensure the crowfoot is fully seated on the fastener before applying torque to prevent rounding. When used with a torque wrench at an offset angle, apply the appropriate torque correction factor per standard mechanical practice. Inspect the wrench for cracks or wear before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Chrome-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 pounds\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: J5338MCF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51544528748850,"sku":"J5338MCF","price":87.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d24aeb732753c08eaa522d9c8d2884bb.jpg?v=1785928866","url":"https:\/\/voomisupply.com\/products\/proto-j5338mcf-open-end-crowfoot-wrench-chrome-metric","provider":"Voomi Supply","version":"1.0","type":"link"}
