It features a 1-8 UNC thread size with full threading along its 1.5-inch length under the head. The 3\/4-inch hex drive accepts a standard hex key or Allen wrench for installation. Constructed from alloy steel with a black oxide coating, this fastener delivers solid tensile strength and moderate corrosion resistance. It meets ASME\/ANSI B18.3 and ASTM A574 dimensional and mechanical standards, making it a reliable choice for precision fastening work across a range of industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for machine assembly, jig and fixture work, tooling, and general industrial maintenance where a socket-drive cap screw is required. The 1-8 UNC coarse thread pitch allows for quick engagement and is well-matched to standard tapped holes in steel, cast iron, and similar ferrous materials. The black oxide finish reduces light reflection and provides light surface protection in dry or mildly corrosive environments. Machinists, maintenance technicians, and fabricators working in manufacturing or production environments will find this fastener fits common assembly requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC coarse thread for fast engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 1.5-inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex socket drive compatible with standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides light corrosion resistance and low reflectivity\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for assemblies requiring a 1-8 UNC hex socket cap screw with a 1.5-inch length under head, suitable for use in ferrous and steel components tapped to ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 3\/4-inch hex key or Allen wrench; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. Confirm that the mating tapped hole is clean, free of debris, and threaded to 1-8 UNC specification before installation. De-energize and lock out any machinery before replacing or installing fasteners on operating equipment. Follow applicable facility or equipment manufacturer guidelines for fastener seating procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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\/4 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, ASTM A574\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: 581807P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695428010290,"sku":"581807P","price":30.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6519f073d02ac3d5e69fe4ed0b946bd2.jpg?v=1788334918","url":"https:\/\/voomisupply.com\/products\/value-collection-581807p-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
