Manufactured from 1006\/1050 grade steel with a galvanized zinc finish, it provides corrosion resistance in both indoor and outdoor environments. The 1\/4-20 UNC thread and square neck beneath the rounded head prevent rotation during tightening without requiring a wrench on the bolt itself. At 7 inches in length under head, this fastener suits deeper assemblies where standard short bolts fall short. It conforms to ASME B18.5 standards for carriage bolt geometry and dimensional tolerances.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is suited for general construction, wood framing connections, playground equipment, deck hardware, and light structural fabrication. The square neck seats into pre-drilled or punched square holes in wood substrates, locking the bolt in place as the nut is driven from the opposite side. Tradespeople, contractors, and maintenance professionals working in corrosive or exterior environments benefit from the galvanized coating, which resists rust and surface oxidation over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for compatibility with standard imperial nuts and hardware\u003c\/li\u003e\n\u003cli\u003eSquare neck design prevents bolt rotation during installation without additional tooling on the head\u003c\/li\u003e\n\u003cli\u003eGalvanized zinc finish provides corrosion resistance for exterior and wet environment use\u003c\/li\u003e\n\u003cli\u003e7-inch length under head accommodates deeper through-bolt assemblies\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank preserves shear strength along the unthreaded body\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.5 dimensional standards for carriage bolts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard imperial carriage bolt for use with 1\/4-20 UNC hex nuts and washers in wood-to-wood and wood-to-metal fastening applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by driving the square neck into a matching square-punched or round-drilled hole in a wood substrate so the head seats flush, then threading a washer and nut from the opposite side. Power down any adjacent electrical systems and follow applicable structural fastening guidelines before beginning work. Do not over-torque the nut, as this can strip the wood fibers surrounding the square neck and allow bolt rotation. A standard wrench or socket is sufficient for nut tightening; no tool is needed on the bolt head.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: 1006\/1050\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 14112CGNFG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723885216050,"sku":"14112CGNFG","price":34740.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/903443020fbeebece5babe6eaf8ca401.jpg?v=1788609344","url":"https:\/\/voomisupply.com\/products\/value-collection-14112cgnfg-carriage-bolt-1-4-20-7in-square-neck","provider":"Voomi Supply","version":"1.0","type":"link"}
