It accepts a 5\/8-inch fastener and features a universal flex-style socket type, giving technicians access to fasteners in tight or angled positions. The socket is machined from alloy steel and finished with a chrome plating that resists corrosion and simplifies cleanup. It meets ASME B107.1 standards for hand socket tools. Licensed tradespeople in HVAC, plumbing, and electrical work rely on this size for equipment panels, flanges, and mechanical connections where a 5\/8-inch hex fastener is common.\u003c\/p\u003e\n\u003cp\u003eThis socket is suited for residential and light commercial service work. It fits standard 3\/8-inch drive tool sets, making it compatible with the ratchets and extensions most technicians already carry. The 12-point geometry engages fasteners at more rotational positions than a 6-point, useful in confined spaces where swing arc is limited. Typical applications include equipment mounting hardware, access panel fasteners, and mechanical assembly work across HVAC, plumbing, and general mechanical trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-inch socket size for common fastener applications in mechanical trades\u003c\/li\u003e\n  \u003cli\u003e12-point design allows engagement at 30-degree increments for use in tight spaces\u003c\/li\u003e\n  \u003cli\u003eUniversal\/flex socket type for angled fastener access\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch drive compatible with standard ratchets, extensions, and breaker bars\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME B107.1 hand tool standards\u003c\/li\u003e\n  \u003cli\u003eChrome finish resists corrosion and wipes clean easily\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8-inch drive ratchets, extensions, and breaker bars.

Always confirm the fastener size matches the socket before applying torque to avoid rounding. De-energize or depressurize any system before removing fasteners from live equipment. Do not use hand sockets with impact drivers unless the socket is impact-rated.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 5\/8 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: J5277A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51544201920818,"sku":"J5277A","price":47.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d5c9806c02dd65d9e94fdf9e4c9fadc.jpg?v=1785925618","url":"https:\/\/voomisupply.com\/products\/proto-j5277a-5-8-in-12-point-3-8-drive-hand-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
