Carriage bolts are designed for through-bolting applications where a smooth, round head is required on the finished side and the square neck resists rotation as the nut is tightened. This fastener meets ASTM A307 standards and is sized in the inch measurement system. It is commonly installed by general contractors, millwrights, carpenters, electricians, and plumbers when fastening wood-to-wood or wood-to-metal assemblies in structural and mechanical applications.\u003c\/p\u003e\u003cp\u003eThis bolt is suited for light-to-medium duty fastening in residential and commercial construction, equipment mounting, and utility installations. The zinc finish provides basic corrosion resistance for interior and protected exterior environments. The 3\/8-16 UNC thread pitch is a widely used coarse thread series, compatible with standard 3\/8-16 hex nuts and washers. This item is sold individually but requires a minimum order quantity of 50 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC coarse thread for broad nut and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e5-inch length under head suits through-bolt applications with moderate material stack thickness\u003c\/li\u003e\n\u003cli\u003eSquare neck prevents bolt rotation during nut tightening without requiring a wrench on the head\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion resistance for general-purpose use\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standards\u003c\/li\u003e\n\u003cli\u003eInch measurement system; package quantity of 1 bolt per unit with a 50-piece minimum order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-16 UNC carriage bolt for general wood-to-wood and wood-to-metal fastening applications; fits standard 3\/8-16 hex nuts and flat washers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, contractors, or maintenance technicians using a standard wrench or socket on the nut side. Drill a clean through-hole sized to match the bolt shank diameter so the square neck seats flush and locks against rotation. Do not over-torque Grade 2 fasteners, as this grade has lower tensile strength than Grade 5 or Grade 8. Always use an appropriately sized flat washer and hex nut on the threaded end to distribute load and prevent pull-through.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5 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 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM A307\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 489084PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698034147634,"sku":"489084PR","price":5468.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d6a17a2c4684809ffa1c0064d3be2c0.jpg?v=1788356985","url":"https:\/\/voomisupply.com\/products\/value-collection-489084pr-carriage-bolt-3-8-16-5in-square-neck","provider":"Voomi Supply","version":"1.0","type":"link"}
