Built from chrome-plated steel, it delivers the corrosion resistance and clean finish that professionals expect on a bench or field tool. At a standard length of 1.75 inches overall, it fits into most engine bay and mechanical service applications without the reach of a deep socket. The 12-point design engages fasteners at twice the indexing positions of a 6-point socket, making it easier to set the tool in tight quarters. It meets AS4984A, ASME B107.110-2012, and SAE AS955 standards and carries a lifetime warranty.\u003c\/p\u003e\n\u003cp\u003eThis socket is suited for general mechanical service work in automotive, fleet, industrial, and equipment maintenance settings. Licensed mechanics, millwrights, and maintenance technicians reach for standard-length sockets like the J5420MN when working on engine components, suspension hardware, and structural fasteners where a 20 mm metric fastener is specified. It is not tether capable, making it most appropriate for ground-level or bench work rather than overhead applications where dropped-tool protocols are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20 mm socket size fits common metric fasteners on automotive and industrial equipment\u003c\/li\u003e\n  \u003cli\u003e12-point design provides more engagement positions in restricted access areas\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches\u003c\/li\u003e\n  \u003cli\u003eChrome-plated steel construction resists corrosion and wipes clean easily\u003c\/li\u003e\n  \u003cli\u003eStandard length at 1.75 inches overall suits the majority of general-service applications\u003c\/li\u003e\n  \u003cli\u003eMeets AS4984A, ASME B107.110-2012, and SAE AS955 standards with a lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hand socket for use with any 1\/2 inch drive ratchet, breaker bar, extension, or torque wrench following standard drive-tool conventions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove this socket by a qualified mechanic or maintenance technician using standard 1\/2 inch drive hand tools. Always confirm the fastener size before applying torque to avoid rounding the fastener head. This socket is not tether capable and should not be used overhead in environments where a dropped-tool program is enforced. Inspect the socket for cracks or deformation before each use and remove it from service if damage is found.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch\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: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTether Style\u003c\/strong\u003e: Not Tether Capable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AS4984A, ASME B107.110-2012, SAE AS955\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\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: J5420MN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541838135602,"sku":"J5420MN","price":21.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b7ee19e60ea18a0b47258ed6b9462fd.jpg?v=1785886435","url":"https:\/\/voomisupply.com\/products\/proto-j5420mn-20mm-12-point-1-2-drive-hand-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
