Crowfoot wrenches give technicians access to fasteners in tight or obstructed spaces where standard box or combination wrenches cannot reach. This set covers sizes from 9 mm through 24 mm, making it useful across a wide range of plumbing, HVAC, and mechanical service work. The open end design seats on two flats of a hex fastener, allowing use where a closed socket would not fit. At 2.33 pounds for the full set, the kit is light enough for a tool pouch or service bag.\u003c\/p\u003e\n\u003cp\u003eThis crowfoot set is suited for residential and light commercial service applications where metric fasteners are common, including refrigerant line fittings, valve packing nuts, pump flanges, and equipment mounting hardware. The 3\/8 inch drive connection pairs with standard ratchets and torque wrenches already found in most trade tool kits, eliminating the need for adapters in the majority of applications. Technicians working on imported equipment or metric-spec HVAC systems will find the 9 mm to 24 mm range covers most recurring fastener sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16-piece set covering 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, and 24 mm\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch drive connection compatible with standard ratchets, extensions, and torque wrenches\u003c\/li\u003e\n  \u003cli\u003eOpen end crowfoot design accesses fasteners in confined or obstructed areas\u003c\/li\u003e\n  \u003cli\u003eContinuous size range from 9 mm to 24 mm reduces gaps in metric coverage\u003c\/li\u003e\n  \u003cli\u003eSet weight of 2.33 pounds keeps the full kit portable for field service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8 inch drive ratchets, torque wrenches, and extensions as an OEM-style metric crowfoot set for general trade service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCrowfoot wrenches are installed by mechanics, HVAC technicians, and plumbers using standard 3\/8 inch drive equipment. Always de-energize or shut off the system being serviced before applying torque to any fastener. Seat the crowfoot fully on the fastener flats before applying force to prevent rounding. When using with a torque wrench at an offset angle, consult the torque wrench manufacturer guidance for any required correction factor.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Type\u003c\/strong\u003e: Open End Crowfoot Wrench Set\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Range\u003c\/strong\u003e: 9 mm to 24 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSizes Included\u003c\/strong\u003e: 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.33 pounds\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: J49000MCF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540383465778,"sku":"J49000MCF","price":623.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f781dd4a2e7c7156c3f45075472a95f4.jpg?v=1785853808","url":"https:\/\/voomisupply.com\/products\/proto-j49000mcf-crowfoot-wrench-set-16-pc-9-24mm","provider":"Voomi Supply","version":"1.0","type":"link"}
