It features a 5\/8-11 UNC thread and a fully threaded shank measuring 3.5 inches in length under the head. The square neck beneath the domed head locks into material to prevent rotation during installation without requiring a wrench on the bolt head. Clear zinc chromate finish provides corrosion resistance. This bolt meets SAE J429 standards and is suited for structural assemblies, heavy equipment mounting, and other demanding mechanical connections handled by millwrights, ironworkers, and maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is appropriate for use in residential construction, commercial fabrication, and industrial maintenance settings where a high-strength fastener is required. The 5\/8-11 thread size and Grade 8 alloy steel construction make it a common choice for steel-to-steel and steel-to-wood connections where load capacity and fastener integrity are critical. The clear zinc chromate coating provides moderate environmental protection in indoor and sheltered outdoor applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC fully threaded shank, 3.5 inches length under head\u003c\/li\u003e\n  \u003cli\u003eSquare neck prevents bolt rotation during nut tightening\u003c\/li\u003e\n  \u003cli\u003eClear zinc chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J429 fastener standard\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; compatible with standard UNC hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC carriage bolt for use with 5\/8-11 nuts and corresponding hardware in structural and mechanical assemblies requiring Grade 8 strength fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, ironworkers, or maintenance mechanics using standard hand or power tools. Insert the bolt through the pre-drilled hole so the square neck seats firmly into the material before applying a nut and washer on the opposite side. Tighten the nut to the appropriate torque specification for the application and joint material as defined by the project engineer or applicable codes. Do not use impact tools at high settings in a way that may damage the square neck seating or strip the thread.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 Coating\u003c\/strong\u003e: Clear Zinc Chromate\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: 0.343 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 217197MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700663746866,"sku":"217197MSC","price":20.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d27ce854db1bebeec84227b74bd10bba.jpg?v=1788393478","url":"https:\/\/voomisupply.com\/products\/value-collection-217197msc-carriage-bolt-5-8-11-3-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
