It is designed to fasten a wooden face to either a wood or metal frame in structural and general construction applications. The flat, domed head eliminates the need for a washer and provides a semi-flush finish. The square underside of the head is self-locking, preventing spinning during installation without requiring a separate driving tool. The galvanized coating delivers corrosion resistance for outdoor and high-moisture environments, though the finish may appear chalky.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for residential and light commercial construction tasks where wood-to-wood or wood-to-metal connections are required. Common applications include deck framing, fence assembly, structural lumber connections, and equipment mounting where a clean, low-profile head finish is preferred. The 100-count pack is intended for contractors and trade professionals working on higher-volume fastening jobs. Units are packaged in boxes of 12 packs per case.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanized finish provides corrosion and rust resistance in outdoor and damp conditions\u003c\/li\u003e\n  \u003cli\u003eFlat domed head eliminates the need for a separate washer and delivers a semi-flush finish\u003c\/li\u003e\n  \u003cli\u003eSquare neck under the head is self-locking to prevent bolt rotation during nut tightening\u003c\/li\u003e\n  \u003cli\u003eNo driving tool required due to the self-locking square underside design\u003c\/li\u003e\n  \u003cli\u003e100 bolts per pack supports higher-volume fastening applications\u003c\/li\u003e\n  \u003cli\u003e5\/16 inches x 2 inches sizing fits standard framing and structural lumber connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for fastening wood-to-wood and wood-to-metal frame assemblies in standard construction and structural applications requiring a 5\/16-inch carriage bolt.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCarriage bolts are typically installed by carpenters, general contractors, or construction tradespeople. Drill a clean hole sized to the bolt diameter before insertion to allow the square neck to seat properly and prevent spinning. Always use an appropriately sized nut and tighten from the nut end only. Follow applicable building codes for structural fastener requirements when used in load-bearing assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Flat domed with square neck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 bolts per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Box (12 packs per case)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 59.2 pounds (case)\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: 812545\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51557919588658,"sku":"812545","price":442.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8fa2bed6175cee9d70c20827d601e06.jpg?v=1786398378","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-812545-galvanized-carriage-bolt-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
