It features an 82-degree flat head with a 3\/8-inch hex socket drive and is manufactured from alloy steel with a black oxide finish for corrosion resistance. The screw measures 5\/8-11 thread size by 4 inches overall length and is partially threaded. Compliant with ASME\/ANSI B18.3 and ASTM F835 standards, this fastener is suited for mechanical assemblies, structural connections, and equipment fabrication where a low-profile head is required.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is used in a wide range of industrial and mechanical applications where a countersunk head is needed to sit flush with or below the mating surface. Typical applications include machine guarding, fixture building, tooling plates, and general equipment assembly. The UNC thread form and alloy steel construction make it appropriate for moderate-to-high-strength fastening in both shop and field environments. Maintenance technicians, machinists, and millwrights commonly install this type of fastener.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head profile for flush or countersunk installations\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive compatible with standard Allen wrenches and hex bits\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved shear strength in through-bolt applications\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 a standard UNC replacement or new-installation flat socket cap screw for use in countersunk fastener applications requiring a 5\/8-11 thread size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8-inch hex key or socket-style Allen driver; ensure the driver is fully seated before applying torque to prevent cam-out and socket damage. Countersink the mating hole to 82 degrees to match the head angle for a proper flush fit. De-energize and lock out any machinery before fastener service per applicable OSHA lockout\/tagout procedures. Inspect threads for damage and apply a thread lubricant or anti-seize compound as appropriate for the application environment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 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: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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, 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: 721264BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699911426354,"sku":"721264BR","price":16.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_d2cfbaad-0ef3-445f-abb3-339aea00ee39.jpg?v=1788383149","url":"https:\/\/voomisupply.com\/products\/value-collection-721264br-flat-socket-cap-screw-5-8-11-x-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
