It features an 82-degree flat head driven by a 5\/8-inch hex socket. The screw is fully threaded, sized at 1-8 UNC x 2-1\/4 inches overall length, and constructed from alloy steel with a black oxide finish. The black oxide coating provides mild corrosion resistance and reduces light reflection. This fastener meets ASME\/ANSI B18.3 and ASTM F835 standards, making it suitable for precision mechanical assemblies where dimensional consistency and strength are required. Machinists, millwrights, and maintenance technicians commonly install this type of fastener.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is used in applications where the screw head must sit flush with or below the surface of the workpiece. Typical install scenarios include machine frames, fixtures, tooling plates, guards, and structural assemblies where a low-profile head is necessary to avoid interference with mating parts or moving components. Its fully threaded shank and UNC thread form make it compatible with standard tapped holes in steel, aluminum, and similar materials common in industrial and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex socket drive for high torque transfer with standard hex keys or socket tooling\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1-8 UNC shank across the 2-1\/4-inch overall length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength in demanding applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1-8 UNC tapped holes requiring a countersunk flat-head fastener.

Ensure the mating tapped hole is clean, properly sized to 1-8 UNC, and that the countersink angle matches the 82-degree flat head geometry before installation. De-energize and lock out any machinery before installing or removing fasteners in live equipment per applicable safety procedures. Do not exceed the torque capacity of the alloy steel fastener or the material of the mating component.\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\u003c\/strong\u003e: 2-1\/4 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 inches\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 721317BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701700624690,"sku":"721317BR","price":45.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_3f3555e1-a141-4390-b71b-784385b23a82.jpg?v=1788403989","url":"https:\/\/voomisupply.com\/products\/value-collection-721317br-flat-socket-cap-screw-1-8x2-1-4","provider":"Voomi Supply","version":"1.0","type":"link"}
