Manufactured from alloy steel with a zinc-plated finish, this fastener resists corrosion while delivering the tensile strength required in demanding environments. It features a 5\/8-11 UNC thread, a 2.5-inch length under head, and a 1\/2-inch hex drive for use with standard hex keys or Allen-style drive tools. The partially threaded shank provides clamping force appropriate for through-bolt and mating-thread applications. Compliance with ASME B18.8 and ASTM A574 confirms dimensional accuracy and mechanical performance standards.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for general mechanical assembly, maintenance and repair operations, and OEM fabrication work across manufacturing, HVAC equipment mounting, electrical enclosure construction, and industrial machinery. The 5\/8-11 UNC thread pitch is a standard coarse-thread configuration widely used in steel-to-steel connections where assembly speed and resistance to cross-threading are priorities. Alloy steel construction makes this fastener appropriate where carbon steel would be insufficient for load or fatigue requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head with partial threading for positive clamping\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive accepts standard Allen keys and hex bit sockets\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 UNC hex socket cap screw for use in any application requiring an ASME B18.8 or ASTM A574 compliant fastener with a 1\/2-inch hex drive and 2.5-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/2-inch hex key, T-handle, or hex bit socket driver. Verify that the mating tapped hole meets 5\/8-11 UNC thread specifications before installation. Apply appropriate thread lubricant or thread-locking compound per the assembly specification. Follow applicable industry torque standards for 5\/8-inch alloy steel fasteners as specified in the equipment or structure design documents.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.8, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 872421BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707154104626,"sku":"872421BR","price":33.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef6720c757834135ee8af4c7b0630447_02b9c45e-9e1e-43f4-8e7a-2832a73aca96.jpg?v=1788438642","url":"https:\/\/voomisupply.com\/products\/value-collection-872421br-hex-socket-cap-screw-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
