Fully threaded along its entire shank, it features a square neck that locks the bolt in place against the work surface as the nut is tightened, eliminating the need to hold the bolt head. The uncoated finish exposes bare steel, making it suitable for applications where a secondary coating, plating, or adhesive will be applied on-site. Manufactured to SAE J429 standards, this fastener is a strong choice for structural assemblies, machinery mounting, and heavy-duty wood-to-metal connections requiring high tensile strength.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is appropriate for heavy-duty industrial, agricultural, and construction applications where Grade 8 strength is specified. Typical uses include equipment frames, implement attachments, structural timber connections, and machinery bases. The 5\/8-11 coarse thread engages quickly in through-hole assemblies and provides solid clamping force under load. It is sized for use with a standard 5\/8-inch heavy hex or hex nut and appropriate hardened flat washer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 alloy steel construction meets SAE J429 for high tensile and proof load requirements\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC coarse thread for fast engagement and strong clamping in through-bolt applications\u003c\/li\u003e\n\u003cli\u003eFully threaded shank allows maximum nut positioning flexibility along the 5-inch length\u003c\/li\u003e\n\u003cli\u003eSquare neck under the domed head seats into the work surface to prevent rotation during installation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for field coating, galvanizing, or adhesive treatment after installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation carriage bolt for through-bolt assemblies requiring a 5\/8-11 UNC thread pattern and Grade 8 alloy steel strength rating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by maintenance mechanics, millwrights, or construction tradespeople using a standard wrench or impact driver on the mating nut. Before installation, confirm the receiving hole diameter is appropriate for a 5\/8-inch fastener and that the work surface material will allow the square neck to seat and lock properly. Always torque to the specification required by the applicable structural or equipment standard, and use a hardened flat washer under the nut to distribute clamping load. Do not weld to this fastener, as heat treatment effects on Grade 8 alloy steel can be compromised by welding.\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: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy 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: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: SAE J429\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.468 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 217258MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720138326322,"sku":"217258MSC","price":16.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1a5ada45c3ebcef2b6f6ab6410139a8.jpg?v=1788560999","url":"https:\/\/voomisupply.com\/products\/value-collection-217258msc-carriage-bolt-5-8-11-5in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
