The square neck beneath the domed head locks the fastener in place as the nut is tightened, preventing rotation without requiring a wrench on the bolt. A zinc-plated finish provides baseline corrosion resistance for general-purpose indoor and outdoor applications. This bolt is sold in a minimum order quantity of 100 pieces, making it suitable for production assembly, structural framing connections, and maintenance stock.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt fits a wide range of light structural, woodworking, and mechanical assembly applications. The 5\/16-18 UNC thread is a standard inch-series coarse thread used across residential and commercial construction, equipment fabrication, and general maintenance work. The square neck is designed to seat into pre-bored square holes in wood or soft substrates, providing a clean, flush dome head on the visible face of the assembly. Installers in construction, HVAC equipment mounting, and general trade work commonly stock this fastener size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head suits moderate material stack thicknesses\u003c\/li\u003e\n  \u003cli\u003eSquare neck seats into wood or soft material to prevent bolt rotation during nut tightening\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction provides medium-strength tensile and shear performance\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers baseline protection against oxidation and light moisture exposure\u003c\/li\u003e\n  \u003cli\u003eSold in 100-piece increments for production, maintenance, and stocking purposes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series carriage bolt for use with 5\/16-18 UNC nuts and washers in wood, light metal, and composite structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires drilling or boring a hole sized to allow the square neck to seat flush and resist rotation. A standard wrench or socket is applied to the nut side only — no tool is used on the dome head. Follow applicable structural codes for torque and fastener spacing when used in load-bearing connections. Inspect the zinc finish for damage before installation in corrosive or high-moisture environments; consider a stainless or hot-dip galvanized fastener for those conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\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: 2 inches\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\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: CAI50310200-100B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710179475762,"sku":"CAI50310200-100B","price":92.56,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec79050595bc964007e2081d5d9b4467.jpg?v=1788463945","url":"https:\/\/voomisupply.com\/products\/value-collection-cai50310200-100b-carriage-bolt-5-16-18-2in","provider":"Voomi Supply","version":"1.0","type":"link"}
