Built to Grade 8 steel specifications, this fastener delivers the tensile strength required for demanding bolted joints where standard hardware falls short. The 5\/8-11 thread size follows the Unified National Coarse (UNC) standard, and the 3-inch length is measured under the head. A zinc yellow dichromate finish provides corrosion resistance for use in both indoor and moderate outdoor environments. This screw is sold in a package quantity of 10 per order.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for heavy-duty mechanical assemblies, equipment mounting, and structural connections where Grade 8 strength is specified. Typical applications include agricultural equipment, automotive chassis work, industrial machinery, and any bolted connection requiring high clamp load. The partial thread design allows for full engagement in thick material sections while maintaining a clean shank in the grip area. Machinists, millwrights, maintenance technicians, and general contractors routinely specify Grade 8 hex cap screws for critical joint applications conforming to ASME B18.2.1 standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread size for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading to preserve shank grip length\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 10 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 UNC hex head cap screw replacement or new-installation fastener for any application specifying Grade 8 steel hardware per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician familiar with torque specifications for Grade 8 fasteners at the 5\/8-11 thread size. Always consult the equipment manufacturer or applicable engineering specification for required torque values before installation. Use a properly sized hex socket or open-end wrench to avoid rounding the head. Ensure mating threads and seating surfaces are clean and free of debris before driving the fastener.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: MP39153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699397165362,"sku":"MP39153","price":30.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89d36d93082bd8a539e510185f72bfd2.jpg?v=1788375445","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39153-hex-cap-screw-5-8-11-x-3-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
