Manufactured from alloy steel with a black oxide coating, this fastener meets ASME\/ANSI B18.3 and ASTM A574 standards. It features a 5\/8-11 UNC thread size, a 2-1\/2 inch length under head, and a 1\/2 inch hex socket drive. The black oxide finish provides mild corrosion resistance and reduces light reflection in exposed installations. This screw is suited for machinists, millwrights, maintenance technicians, and industrial assembly professionals working with standard inch-series fastening systems.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is commonly used in machine tool assembly, fixture building, equipment mounting, and general industrial fabrication where a flush or recessed fastener head is required. The partial threading allows for shank engagement across joined materials, improving clamping force in thick-stock applications. It is appropriate for both shop and field use wherever UNC inch-series socket cap screws are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread size for standard inch-series fastening\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch length under head with partial threading for improved clamping\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch hex socket drive for use with standard Allen or hex-key tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for mild corrosion resistance and reduced glare\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series socket cap screw suitable for use in any application requiring a 5\/8-11 UNC partially threaded hex socket fastener conforming to ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 1\/2 inch hex key or Allen wrench; confirm the driver is fully seated in the socket before applying torque to avoid rounding. Always verify thread engagement depth and hole preparation meet the requirements of the applicable assembly drawing or engineering specification. De-burr and clean threaded holes before installation to ensure proper seating and accurate torque transfer. Follow applicable industry or facility standards for fastener reuse and inspection after removal.\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 Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 pounds\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: 011421BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695448654130,"sku":"011421BR","price":34.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16ed11ab4a99cf6c9a4f471d2c79163a.jpg?v=1788335149","url":"https:\/\/voomisupply.com\/products\/value-collection-011421br-hex-socket-cap-screw-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
