Built for use with 1\/2 inch drive impact wrenches and rattle guns, this socket accepts 20mm fasteners and measures 1.5 inches in overall length. The 12-point geometry engages hex fasteners from multiple positions, reducing setup time in tight or awkward access situations. At 0.18 pounds, the J7420MT is compact enough for overhead and confined-space work without sacrificing the wall thickness required to handle impact torque loads. Mechanics, pipefitters, and industrial maintenance techs will find this socket a reliable addition to a standard impact drive set.\u003c\/p\u003e\n\u003cp\u003eThis socket is suited for automotive, fleet maintenance, mechanical contracting, and general industrial service work where a 1\/2 inch drive impact tool is standard. The 20mm size is common on metric-fastened equipment including trucks, heavy machinery, pipe flanges, and structural assemblies. It is sold individually, making it a practical replacement for a worn or missing socket without requiring a full set purchase.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch drive fits standard impact wrenches and extensions\u003c\/li\u003e\n  \u003cli\u003e20mm socket size for metric fastener applications\u003c\/li\u003e\n  \u003cli\u003e12-point design allows multiple engagement positions on hex fasteners\u003c\/li\u003e\n  \u003cli\u003e1.5 inch overall length suits standard-depth fastener access\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.18 pounds for extended use and portability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2 inch drive impact wrenches, extensions, and adaptors in professional mechanical and industrial service applications requiring a 20mm metric socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using a 1\/2 inch drive impact wrench or breaker bar. Verify the socket is fully seated on the fastener before applying torque to avoid rounding. Inspect the socket for cracks or wear before each use, and replace any socket showing visible deformation. Do not use impact sockets with hand-ratchet tools not rated for impact loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\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: J7420MT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51544508891442,"sku":"J7420MT","price":21.27,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c490c8d3b2a1652673494bf4ab2ff8a.jpg?v=1785928512","url":"https:\/\/voomisupply.com\/products\/proto-j7420mt-impact-socket-1-2-in-drive-20mm-12-pt","provider":"Voomi Supply","version":"1.0","type":"link"}
