It features a 1\/2-20 UNF thread size with a 3-inch length under head and partial threading along the shank. The drive is a 3\/8-inch hex socket, requiring a standard hex key or Allen driver for installation. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and surface hardness suited for demanding shop-floor and field environments. Licensed tradespeople and maintenance mechanics rely on this fastener where a clean, recessed drive head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for general industrial, mechanical, and maintenance applications where a partially threaded, socket-drive cap screw is specified. It fits assemblies that call for 1\/2-20 UNF thread engagement and a low-profile recessed head. Common use cases include machine frames, tooling fixtures, equipment housings, and structural brackets. The partial threading provides a shoulder section useful for alignment and shear-load applications. This fastener meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for engineered assemblies with defined fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF thread for fine-pitch engagement and strong clamping force\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading for shoulder and shear applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish adds surface corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3, ASTM A574, and IFI 124 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hex socket cap screw for any mechanical assembly or structural application specifying a 1\/2-20 UNF partially threaded socket cap screw per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/8-inch hex key or Allen driver; use a torque wrench calibrated to the assembly specification for the fastener grade. Power down and de-energize any machinery before accessing fastener locations on live equipment. Ensure mating threads are clean and free of debris before threading to avoid galling the alloy steel. Follow applicable mechanical codes and the equipment manufacturer's torque requirements for the specific assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inches\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\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 015407PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694671266098,"sku":"015407PR","price":524.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddfddf2de4f5c9e16072112a9ecaa412.jpg?v=1788326961","url":"https:\/\/voomisupply.com\/products\/value-collection-015407pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
