Built from alloy steel with a chrome-plated finish, this socket meets ASME B107.1 standards for hand socket tools. The 3\/8-inch drive size makes it compatible with a wide range of standard ratchets and extensions. With a compact profile and universal flex compatibility, it delivers reliable torque transfer on hex and 12-point fasteners. Technicians across plumbing, HVAC, electrical, and general mechanical trades rely on this socket for its durability and consistent fit on 3\/4-inch fasteners.\u003c\/p\u003e\n\u003cp\u003eThe J5279A is suited for residential and commercial service environments where a 3\/8-inch drive 3\/4-inch socket is required. It is commonly used on equipment panels, mechanical assemblies, pipe fittings, and structural fasteners. The 12-point design allows engagement from more positions than a 6-point socket, which is useful in tight access areas. Sold individually, this socket fits standard 3\/8-inch drive ratchets, breaker bars, and torque wrenches used by licensed tradespeople on job sites and in service shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch socket size for standard hex fasteners\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch drive for compatibility with common ratchets and extensions\u003c\/li\u003e\n  \u003cli\u003e12-point design allows more engagement positions in confined spaces\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high torque durability\u003c\/li\u003e\n  \u003cli\u003eChrome-plated finish resists corrosion and simplifies cleaning\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B107.1 standards for hand socket tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or addition for any 3\/8-inch drive tool set requiring a 3\/4-inch 12-point hand socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis socket is installed by hand tool technicians and licensed tradespeople using standard 3\/8-inch drive ratchets, extensions, or torque wrenches. Before use, verify the fastener size matches the 3\/4-inch socket opening to prevent rounding. Ensure the socket is fully seated on the drive before applying torque. Inspect the socket for cracks or wear before each use, and do not use impact drivers with a hand-rated socket.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Type\u003c\/strong\u003e: Universal\/Flex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Chrome-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B107.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: J5279A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541187854642,"sku":"J5279A","price":49.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f458825369a1d5097a7073957f47ab4.jpg?v=1785869733","url":"https:\/\/voomisupply.com\/products\/proto-j5279a-3-4-in-3-8-drive-12-point-chrome-hand-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
