It features a 1-8 UNC thread size and a 14-inch length under head, making it suitable for deep-grip installations where standard-length fasteners fall short. The screw is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces surface reflectivity. A 3\/4-inch hex drive socket is required for installation. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards and is installed by maintenance technicians, millwrights, and mechanical contractors across a wide range of industries.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in machine building, equipment maintenance, heavy fabrication, and general industrial assembly where a high-tensile socket head fastener is required. The partial threading allows for a smooth shank section that supports shear load distribution in bolted joints. Its long 14-inch under-head length is especially useful in applications involving thick stock, stacked components, or deep clearance holes where a standard-length screw would not reach full thread engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread form for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e14-inch length under head accommodates deep-reach fastening requirements\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear load distribution in bolted joints\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength per ASTM A574\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and a low-glare surface\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 dimensional standards for socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1-8 UNC hex socket cap screw for use in any application requiring an ASME\/ANSI B18.3 and ASTM A574 compliant fastener with a 14-inch under-head length and 3\/4-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/4-inch hex key or socket driver of appropriate length for the joint depth. De-energize and lock out any machinery before servicing fastened assemblies. Verify that mating tapped holes conform to 1-8 UNC tolerance class before assembly. Apply thread lubricant or anti-seize compound as required by the equipment manufacturer or applicable maintenance specification to prevent galling on alloy steel threads.\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: 14 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\/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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\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  \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: 581823BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714316206386,"sku":"581823BR","price":59.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5c8266c48f1e004fa53a3358f000026.jpg?v=1788499360","url":"https:\/\/voomisupply.com\/products\/value-collection-581823br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
