It features a round dome head and a square neck that bites into wood or soft material to prevent rotation during installation. The coarse thread pattern provides strong holding power in wood-to-wood and wood-to-metal connections. This bolt is a standard choice for structural fastening tasks in residential construction, decking, framing, and general fabrication. Carpenters, general contractors, and maintenance technicians typically keep these on hand for high-volume fastening applications where consistent clamping force is required.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for through-bolt applications in wood framing, deck ledger connections, post-and-beam assemblies, and similar structural joints. The coarse 3\/8-16 thread mates with standard hex nuts and washers. The 50-pack quantity makes it practical for job-site use where multiple fasteners of the same size are needed in a single session.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 coarse thread for strong engagement in wood and soft substrates\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length suits through-bolt applications in dimensional lumber\u003c\/li\u003e\n  \u003cli\u003eRound dome head provides a low-profile, finished appearance on the face side\u003c\/li\u003e\n  \u003cli\u003eSquare neck locks into material to prevent spinning during nut tightening\u003c\/li\u003e\n  \u003cli\u003eSteel construction for reliable tensile strength in structural connections\u003c\/li\u003e\n  \u003cli\u003e50-pack quantity reduces job-site restocking interruptions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 coarse-thread carriage bolt compatible with matching hex nuts, coupling nuts, and flat washers following ASME B18.5 dimensional standards for round-head square-neck bolts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCarriage bolts are installed by driving the bolt through a pre-drilled hole sized to the shank diameter, then seating the square neck flush by tapping the head with a hammer. A flat washer and hex nut are threaded onto the exposed end and tightened with a wrench — no wrench is needed on the head side once the neck is seated. Follow applicable building code requirements, including IRC or IBC provisions, when using carriage bolts in load-bearing or ledger connections. Do not overtighten in soft wood species, as the square neck can pull through the substrate.\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\u003eLength\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Round Dome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Style\u003c\/strong\u003e: Square Neck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 59.4 pounds\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: HILLMAN FASTENERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 240183\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51558679839026,"sku":"240183","price":320.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9aca8f191d19b3273a5ee28d9093e57_60bec2a1-3052-434b-93ab-6f1344f2231b.jpg?v=1786417776","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-240183-carriage-bolt-3-8-16-x-4-1-2-in-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
