It features an 82-degree flat head with a 3\/8-inch hex socket drive, and is fully threaded along its 3-inch overall length. The 5\/8-18 UNF thread specification suits fine-thread applications where vibration resistance or precise clamping force is required. Manufactured from alloy steel with a black oxide finish, this screw delivers solid mechanical strength with moderate corrosion resistance in protected environments. Installation is handled by machinists, millwrights, and general maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for use in machine frames, fixtures, jigs, and assemblies where a low-profile head is required to sit flush with or below the mating surface. The fully threaded design maximizes thread engagement across the full 3-inch length, making it appropriate for through-hole applications or deep-threaded blind holes. The black oxide finish reduces light reflection and provides mild surface protection, a common requirement in industrial and tooling environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for high-torque engagement with a standard Allen key or hex bit\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3-inch overall length for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for vibration-resistant clamping\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM F835 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion resistance and low reflectivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or stock fastener for any application requiring an 82-degree flat socket cap screw in 5\/8-18 UNF thread per ASME\/ANSI B18.3 and ASTM F835.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 3\/8-inch hex key or hex drive bit. Ensure the mating countersink is machined to an 82-degree included angle for proper head seating. De-energize or lock out any equipment before fastener removal or installation per applicable OSHA lockout\/tagout procedures. Do not reuse fasteners that show signs of galling, thread damage, or corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 721282BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703159882034,"sku":"721282BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_beb3d466-54f1-4b95-b894-f33021aab0ad.jpg?v=1788415142","url":"https:\/\/voomisupply.com\/products\/value-collection-721282br-flat-socket-cap-screw-5-8-18","provider":"Voomi Supply","version":"1.0","type":"link"}
