It features a 5\/8-11 UNC thread size with a 2-1\/2 inch length under the head and is driven by a 1\/2-inch hex (Allen) drive. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and moderate corrosion resistance. It is partially threaded, which is the standard configuration for cap screws of this diameter and length. Machinists, millwrights, maintenance technicians, and fabricators install these in machine tool fixtures, equipment frames, and precision assemblies where a flush or recessed fastener head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in manufacturing facilities, maintenance shops, and fabrication environments. The 5\/8-11 UNC coarse thread is widely used in general industrial machinery and steel-to-steel fastening. The black oxide coating reduces light reflection and provides mild corrosion resistance in dry or lightly oiled environments. This fastener meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for applications that require documented fastener compliance. It is sold individually but must be ordered in multiples of 10.\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\u003e2-1\/2 inch length under head with partial threading — standard for this size class\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive accepts standard hex keys and socket drive tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-reflectance appearance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3, ASTM A574, and IFI 124 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-purpose hex socket cap screw for any application using a 5\/8-11 UNC tapped hole requiring a 2-1\/2 inch grip length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 1\/2-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated torque specifications for the alloy steel grade being used — consult applicable fastener torque tables for ASTM A574 socket head cap screws. Follow all applicable facility safety and equipment lockout\/tagout procedures before servicing any assembly.\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: 2-1\/2 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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\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: 015421BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714320498994,"sku":"015421BR","price":36.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ae060aa44a6ce39d6d90be9a107f2cd.jpg?v=1788499457","url":"https:\/\/voomisupply.com\/products\/value-collection-015421br-hex-socket-cap-screw-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
