The set covers inch sizes from 1\/4 inch to 3\/4 inch and metric sizes from 10 mm to 19 mm, giving technicians a broad range without switching drive sizes. All sockets are 6-point, which delivers better torque transfer and reduces fastener rounding under impact load. Constructed from steel, the set includes a socket bar and clips for organized storage. A lifetime warranty backs the entire set. HVAC, plumbing, and electrical professionals who work in tight mechanical rooms or on equipment panels will find this dual-measurement coverage practical for daily service calls.\u003c\/p\u003e\n\u003cp\u003eThis socket set suits trade professionals who need both inch and metric coverage from a single tray. It is appropriate for residential and light commercial service work including air handler installations, condensing unit mounting hardware, panel work, and pump or fixture connections. The included sizes address the fastener variety commonly encountered on equipment manufactured to both SAE and metric standards. The socket bar and retaining clips keep individual sockets indexed and ready during fast-paced service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-piece set with 3\/8 inch drive covers both inch and metric fasteners in one kit\u003c\/li\u003e\n  \u003cli\u003e6-point socket geometry reduces fastener rounding under impact torque\u003c\/li\u003e\n  \u003cli\u003eRated for both impact and standard hand-tool use\u003c\/li\u003e\n  \u003cli\u003eInch sizes: 1\/4, 5\/16, 3\/8, 7\/16, 1\/2, 9\/16, 5\/8, 11\/16, and 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003eMetric sizes: 10, 11, 12, 13, 14, 15, 17, 18, and 19 mm\u003c\/li\u003e\n  \u003cli\u003eIncludes socket bar and clips for organized storage and quick retrieval\u003c\/li\u003e\n  \u003cli\u003eBacked by a lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any 3\/8 inch drive impact wrench, ratchet, or breaker bar.

Confirm the socket is fully seated on the fastener before applying torque to prevent slippage and personal injury. Use impact-rated sockets only with impact drivers and wrenches — do not substitute chrome hand-tool sockets under impact load. Follow applicable NEC, IFGC, or IPC guidelines when working on regulated systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Size (Inch)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Size (Inch)\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Size (Metric)\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Size (Metric)\u003c\/strong\u003e: 19 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Type\u003c\/strong\u003e: Impact and Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Inch and Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Socket Bar and Clips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 13.4 inches L x 4 inches W x 1.9 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\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: J72230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541351792946,"sku":"J72230","price":138.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cacb5ad125e74b09f9ac179aa30569e.jpg?v=1785873266","url":"https:\/\/voomisupply.com\/products\/proto-j72230-impact-socket-set-18-pc-3-8-in-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
