It features a 1\/2-20 UNF thread size with a 2.5-inch length under head and a 3\/8-inch hex drive. The fastener is manufactured from alloy steel with a black oxide finish, providing a combination of tensile strength and corrosion resistance suitable for demanding service environments. This screw is partially threaded, which helps maintain clamping force in through-bolt applications. Machinists, millwrights, and maintenance technicians are the typical installers for this class of fastener.\u003c\/p\u003e\u003cp\u003eThis socket cap screw is suited for use in precision mechanical assemblies, machine frames, hydraulic component mounting, and fixture work where a recessed drive and high clamp load are required. The 1\/2-20 UNF fine thread pitch offers better thread engagement and torque control compared to coarse thread equivalents, making it a preferred choice in applications where vibration resistance and precise axial loading matter. It is appropriate for both new construction and maintenance-repair-overhaul work across industrial and commercial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-20 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n\u003cli\u003e2.5-inch length under head with partial threading for strong clamping in through-bolt configurations\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for use with standard Allen keys and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength in demanding mechanical applications\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection on exposed fasteners\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3, ASTM A574, and IFI 124 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard hex socket cap screw conforming to ASME\/ANSI B18.3, ASTM A574, and IFI 124, suitable for use in any application requiring a 1\/2-20 UNF partially threaded socket cap screw with a 3\/8-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists or maintenance technicians using a properly sized 3\/8-inch hex key or socket bit. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or thread-locking compound as required by the assembly specification. Do not exceed the fastener's rated proof load, and use a calibrated torque wrench when specified torque values are provided by the equipment manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2.5 inches\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\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\u003eFastener Standards\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 015405PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716571595058,"sku":"015405PR","price":1792.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b49b97e50ece0a4dd9c9104a5a048ef.jpg?v=1788528104","url":"https:\/\/voomisupply.com\/products\/value-collection-015405pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
