It features an 82-degree flat head driven by a 5\/8-inch hex socket and is fully threaded along its 2-1\/2-inch overall length. The thread size is 1-8 UNC, machined from alloy steel and finished in black oxide for corrosion resistance and reduced light reflection. This screw meets ASME\/ANSI B18.3 and ASTM F835 standards. It is installed by machinists, maintenance technicians, and fabricators working in industrial, mechanical, and structural assembly environments.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is suited for use in machine assemblies, tooling fixtures, jigs, and mechanical enclosures where the fastener head must sit flush with or below the mating surface. The UNC thread form and alloy steel construction make it appropriate for high-load, precision-fit applications. The black oxide finish is commonly selected in applications where surface glare must be minimized or where a uniform dark appearance is preferred alongside other black oxide hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head sits flush with mating surface when installed in a properly countersunk hole\u003c\/li\u003e\n\u003cli\u003e5\/8-inch hex socket drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n\u003cli\u003eFully threaded 2-1\/2-inch overall length for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003e1-8 UNC thread standard for broad compatibility with inch-system tapped holes\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength in demanding applications\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F835 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and aftermarket replacement flat socket cap screw for inch-system assemblies requiring a 1-8 UNC, 2-1\/2-inch fully threaded countersunk fastener conforming to ASME\/ANSI B18.3 and ASTM F835.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or mechanical assemblers using a calibrated hex key or T-handle socket driver sized to 5\/8 inch. The mating hole should be properly countersunk to 82 degrees before installation to ensure full head seating. Power down or de-energize any equipment before servicing assemblies containing this fastener. Do not exceed the rated torque range for the alloy steel grade and thread size per applicable industry references.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2-1\/2 inches (overall)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82 degree Flat\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: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F835\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 721318BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705330336050,"sku":"721318BR","price":46.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_c2e76161-1438-48e5-b470-6bfa0fe3f87f.jpg?v=1788428303","url":"https:\/\/voomisupply.com\/products\/value-collection-721318br-flat-socket-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
