Sized at 5\/8-11 thread with a 2-inch length under head, this fastener is manufactured from Grade 8 steel in a bright, uncoated finish. Grade 8 designation indicates a medium-carbon alloy steel with proof load and tensile strength ratings suited for demanding bolted joints. The Unified National Coarse (UNC) thread form and ASME B18.2.1 compliance ensure dimensional accuracy and interchangeability with standard hex nuts and threaded components. Sold in packs of 10.\u003c\/p\u003e\u003cp\u003eThis fastener is commonly used in heavy equipment assembly, machinery mounting, structural steel connections, and general fabrication work where high-strength hardware is required. The fully threaded body allows maximum thread engagement across the full 2-inch shank length, making it well suited for through-bolting and short-grip applications. Tradespersons in HVAC equipment installation, mechanical contracting, and equipment rigging frequently rely on Grade 8 hex cap screws for structural connections that must meet specified torque and clamp-load requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 for compatibility with standard hex nuts and threaded inserts\u003c\/li\u003e\n\u003cli\u003eFully threaded 2-inch shank maximizes thread engagement in short-grip applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for dry indoor environments and painted assemblies\u003c\/li\u003e\n\u003cli\u003eASME B18.2.1 compliant for dimensional interchangeability\u003c\/li\u003e\n\u003cli\u003eSold in a convenient 10-piece pack quantity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5\/8-11 UNC hex head cap screw per ASME B18.2.1, compatible with any standard 5\/8-11 hex nut, threaded insert, or tapped hole conforming to Unified National Coarse thread specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical or trade personnel using a calibrated torque wrench to achieve the specified clamp load for Grade 8 fasteners. Always inspect mating threads for damage or contamination before assembly. Apply thread lubricant or anti-seize only if required by the joint specification, as lubrication affects torque-to-clamp-load calculations. Do not mix Grade 8 fasteners with lower-grade nuts or hardware in high-load joints.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 inches\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: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: MP99149\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701047623986,"sku":"MP99149","price":25.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0d195a467f09809148169a960a32f46.jpg?v=1788397392","url":"https:\/\/voomisupply.com\/products\/value-collection-mp99149-hex-head-cap-screw-5-8-11-x-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
