Built from alloy steel with a black oxide finish, this standard-length socket delivers the durability and corrosion resistance that trade professionals require. The 12-point geometry provides six additional contact positions compared to a 6-point socket, allowing faster engagement in confined spaces. It is driven by a 1\/2 inch drive and meets ASME B107.1 standards for hand socket tools. Weight is 0.51 pounds.\u003c\/p\u003e\u003cp\u003eThis socket is suited for heavy-duty fastening tasks encountered in mechanical contracting, industrial maintenance, fleet service, and general construction. The 1-1\/4 inch drive size makes it appropriate for large structural fasteners, heavy equipment, and commercial plumbing or HVAC applications where a 1\/2 inch drive torque wrench or ratchet is the standard tool. The standard length profile fits most open access fastener locations without requiring an extension.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch socket size for large fastener applications\u003c\/li\u003e\n\u003cli\u003e12-point design for quick engagement and multiple drive positions\u003c\/li\u003e\n\u003cli\u003e1\/2 inch drive compatibility with standard ratchets and torque wrenches\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high-strength, heavy-duty use\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for corrosion resistance and reduced glare\u003c\/li\u003e\n\u003cli\u003eMeets ASME B107.1 hand socket standards\u003c\/li\u003e\n\u003cli\u003eBacked by a limited lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style replacement or addition for professional 1\/2 inch drive hand socket sets requiring a 1-1\/4 inch, 12-point socket.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove fasteners using a compatible 1\/2 inch drive ratchet, breaker bar, or torque wrench. Ensure the fastener head is fully seated in the socket before applying torque to prevent rounding. Always de-energize, depressurize, or lock out equipment before working on mechanical connections. Inspect the socket for cracks or deformation before each use and replace if damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 1-1\/4 inches\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: 1-21\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\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: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.51 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTether Style\u003c\/strong\u003e: Not Tether Capable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Limited Lifetime\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: J5440B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541821554994,"sku":"J5440B","price":30.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03cce5699fc8c2edfae9e63f7c00a74d.jpg?v=1785885868","url":"https:\/\/voomisupply.com\/products\/proto-j5440b-1-1-4-in-12-point-hand-socket-1-2-in-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
