It features a 1\/2-20 UNF thread size with a 1-3\/4 inch length under head and is fully threaded from head to end. The 3\/8 inch hex drive accepts a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide finish, this fastener resists corrosion and maintains dimensional integrity under load. Licensed trades and maintenance technicians reach for this style of cap screw when securing machine components, fixtures, and structural assemblies where a flush or recessed fastener head is required.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is suited for precision mechanical and industrial applications where fine-thread engagement is needed. The 1\/2-20 UNF thread pitch provides tighter thread spacing than coarse-thread equivalents, making it appropriate for applications requiring precise clamping force control or use in harder materials. It is commonly installed in manufacturing equipment, hydraulic components, pump housings, and general mechanical assemblies by machinists, millwrights, and maintenance technicians working to ASME and ASTM fastener standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine thread for precise clamping and use in hard materials\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head, fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener for mechanical assemblies requiring 1\/2-20 UNF socket cap screws conforming to ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 3\/8 inch hex key or hex drive bit. Always de-energize, depressurize, or otherwise make safe any assembly before removing or replacing fasteners. Do not mix UNF and UNC thread fasteners in the same tapped hole. Verify thread engagement length and mating material hardness before installation to avoid stripping or galling.\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: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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 Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 011399PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723953209650,"sku":"011399PR","price":5891.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1e6566647ce302808ae6f64be745c2a.jpg?v=1788610535","url":"https:\/\/voomisupply.com\/products\/value-collection-011399pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
