Made from Grade 5 steel with a zinc-plated finish, this bolt is designed for structural fastening applications where a smooth, dome-shaped head and anti-rotation neck are required. The UNC thread standard ensures wide tool and nut compatibility. Installers rely on carriage bolts like this one when a flush, tamper-resistant head face is needed on the accessible side of a joint.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for wood-to-wood, wood-to-metal, and light structural connections in residential and commercial construction, HVAC equipment mounting, electrical enclosure assembly, and general mechanical fastening. The square neck bites into wood or pre-drilled soft materials to prevent rotation during nut tightening without requiring a wrench on the bolt head. Sold in multiples of 50 per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for broad nut and hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eSquare neck resists rotation in wood and soft-material assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 strength requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance in dry or mildly humid environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC carriage bolt compatible with 3\/8-16 hex nuts, washers, and hardware conforming to inch-system fastener standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCarriage bolts are typically installed by tradespeople and general contractors using standard hand tools. Drill or punch a clearance hole sized for the bolt shank, insert the bolt so the square neck seats firmly into the material, then thread and tighten a compatible 3\/8-16 nut from the opposite side. Do not apply a wrench or impact to the bolt head, as this will damage the dome profile and may break the square neck seat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 1-3\/4 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\u003eStandard\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\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: CAI503701750-050B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690726588722,"sku":"CAI503701750-050B","price":50.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_b4f97a25-fcc9-4aa9-8766-4c5937588b41.jpg?v=1788274513","url":"https:\/\/voomisupply.com\/products\/value-collection-cai503701750-050b-carriage-bolt-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
