Built from alloy steel with a black oxide finish, it provides solid corrosion resistance and durability in demanding environments. The screw features an 82-degree flat head driven by a 9\/16-inch hex socket, follows UNC thread standards at 7\/8-9, and measures 5 inches in overall length with partial threading. It meets ASME\/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and maintenance technicians typically install these fasteners in machine assemblies, fixtures, and structural components where a low-profile head is necessary.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is suited for general industrial and mechanical applications requiring a countersunk fastener. Its partially threaded shank helps maintain accurate alignment and clamping in through-hole or tapped applications. The black oxide finish reduces surface reflectivity and offers mild corrosion protection in dry or lightly oiled environments. Typical use cases include machine frames, jigs, fixtures, and equipment enclosures where the fastener must sit flush with or below the mating surface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head profile for countersunk, flush-mount installations\u003c\/li\u003e\n\u003cli\u003e9\/16-inch hex socket drive for high-torque application with standard Allen keys or hex bits\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for strength in structural and mechanical assemblies\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and low surface reflectivity\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank supports accurate alignment and clamping force\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard fastener for industrial machinery, fixtures, and equipment requiring a 7\/8-9 UNC flat socket cap screw with a 5-inch overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists or maintenance technicians familiar with UNC threaded fasteners. Ensure the mating hole is properly countersunk to 82 degrees before installing. Apply appropriate thread lubricant or fastener-grade adhesive as required by the application. Do not exceed the rated torque range for the fastener grade and never install into damaged or misaligned threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\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: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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: 721312BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716253974834,"sku":"721312BR","price":21.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_be00620c-4490-47ba-8416-a48fe192a8e0.jpg?v=1788523606","url":"https:\/\/voomisupply.com\/products\/value-collection-721312br-flat-socket-cap-screw-7-8-9-x-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
