The square neck beneath the domed head locks into a square hole in wood or soft material, preventing rotation during nut tightening without requiring a wrench on the bolt side. A zinc trivalent chromate finish provides corrosion resistance for general industrial and structural applications. This bolt is fully threaded along its 2-inch shank length, meeting SAE J429 standards for Grade 8 fastener performance. It is used by maintenance technicians, millwrights, contractors, and fabricators in applications that demand high-strength fastening.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for structural connections in wood-to-metal and wood-to-wood assemblies where a flush, rounded head profile is required on the visible face. Common applications include equipment mounting, trailer fabrication, agricultural equipment repair, and general structural assembly work. The Grade 8 alloy steel construction handles high-load and high-stress environments where lower-grade fasteners would be insufficient. The SAE J429 compliance makes it appropriate for use in applications governed by engineering or construction standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel for high tensile strength in demanding structural applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread — coarse thread series for fast assembly and strong engagement\u003c\/li\u003e\n  \u003cli\u003eFully threaded 2-inch shank provides maximum thread engagement flexibility\u003c\/li\u003e\n  \u003cli\u003eSquare neck beneath head prevents rotation during installation without a secondary tool\u003c\/li\u003e\n  \u003cli\u003eZinc trivalent chromate finish delivers corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J429 Grade 8 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 UNC carriage bolt for use in wood, composite, and light metal substrates where a square-neck anti-rotation fastener of Grade 8 strength is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCarriage bolts are installed by driving the square neck flush into a square-punched or drilled hole so the head seats flat and the neck locks against rotation. A washer and nut are applied to the threaded end and tightened with a wrench or impact tool — no tool is needed on the head side once the neck is seated. Follow applicable structural or equipment torque specifications from the project engineer or OEM documentation, as this input data does not specify a torque value. Always ensure the mating hole is sized correctly for the square neck to prevent spinning under load.\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\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\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: Zinc Trivalent Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.218 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: 217137MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691197268274,"sku":"217137MSC","price":17.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94ee77dad00547d98ed0becb32696267_88da3209-33dd-49b0-b0b7-4b86e9aa8a0c.jpg?v=1788281342","url":"https:\/\/voomisupply.com\/products\/value-collection-217137msc-carriage-bolt-5-8-11-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
