It features a 1\/2-13 UNC thread and a full 8-inch length under head, making it well suited for structural connections that demand a smooth, flush bearing surface. The square neck locks the bolt against rotation when drawn through wood or soft material, eliminating the need for a wrench on the bolt head. A zinc trivalent chromate finish provides corrosion resistance. This bolt meets SAE J429 standards and is fully threaded along its entire 8-inch shank. Licensed tradespeople and maintenance professionals install this type of hardware across a wide range of structural and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is appropriate for use in residential and light commercial construction, equipment mounting, decking, framing connections, and general fabrication work where a Grade 8 tensile rating is required. The fully threaded shank allows maximum thread engagement at any grip length within the bolt's reach. The 1\/2-13 UNC thread pattern accepts standard hex nuts and washers stocked at most trade supply counters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high-strength fastening requirements\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC fully threaded shank, 8 inches length under head\u003c\/li\u003e\n  \u003cli\u003eSquare neck prevents rotation during installation without a secondary tool on the bolt head\u003c\/li\u003e\n  \u003cli\u003eZinc trivalent chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J429 fastener standard\u003c\/li\u003e\n  \u003cli\u003eSmooth domed head provides a clean bearing surface and aesthetic finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC carriage bolt compatible with any application requiring a Grade 8 alloy steel fastener at 8 inches length under head per SAE J429 specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by carpenters, ironworkers, millwrights, or maintenance mechanics using standard hand or power tools. Always de-energize any adjacent electrical systems and relieve pressure from any connected mechanical systems before working in the fastener area. Drive the square neck firmly into the substrate to seat it before applying torque to the nut. Use a flat washer and properly rated nut on the threaded end and follow applicable structural or mechanical codes for torque and fastener spacing requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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: 8 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: Zinc Trivalent Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161603\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: 216377MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51747503636786,"sku":"216377MSC","price":1163.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94ee77dad00547d98ed0becb32696267_92f91584-ec27-454f-9000-f5fbf8b3e74b.jpg?v=1788881478","url":"https:\/\/voomisupply.com\/products\/value-collection-216377msc-carriage-bolt-1-2-13-8-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
