The screw features a 1-1\/2-12 UNF thread and measures 4.5 inches under the head with full threading along the entire shank. Drive engagement is accomplished with a 1-inch hex socket drive. Constructed from alloy steel and finished with a black oxide coating, this fastener delivers solid tensile strength and basic corrosion resistance for demanding shop and field applications. It is installed by licensed mechanics, machinists, and maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in industrial machinery, precision fixtures, hydraulic equipment, and structural assemblies where a fine-thread UNF pattern is required. The 1-1\/2-12 UNF thread pitch provides tighter clamping force and greater resistance to vibration loosening compared to coarse-thread equivalents, making it a common choice in applications subject to dynamic loading. The black oxide finish is appropriate for interior or protected environments where surface appearance and light corrosion inhibition are needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-12 UNF fine thread for high clamping force and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the entire 4.5-inch length under head\u003c\/li\u003e\n  \u003cli\u003e1-inch hex socket drive compatible with standard socket tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides a matte surface and light corrosion inhibition\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 direct-fit fastener for applications requiring a 1-1\/2-12 UNF hex socket cap screw per 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 1-inch hex key or socket driver. Always de-energize and lock out any powered equipment before servicing fastened assemblies. Verify thread engagement and mating thread condition before torquing. Do not substitute a coarse-thread fastener in a UNF-tapped hole, as thread mismatch will result in fastener failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-12 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 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: 1 inch\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 Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.003 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: 581966BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704650858802,"sku":"581966BR","price":72.11,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_5940c134-fe7b-4004-b5ab-f1a9899f8b27.jpg?v=1788424069","url":"https:\/\/voomisupply.com\/products\/value-collection-581966br-hex-socket-cap-screw-1-1-2-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
