It features a domed head and a square neck that bites into the material surface to prevent rotation during tightening, eliminating the need for a wrench on the bolt end. The shank measures 8.5 inches in length under head with a 1\/2-13 UNC thread form. Constructed from Grade 2 steel with a zinc-plated finish, this bolt meets ASTM A307 standards and is suited for general-purpose structural and construction fastening tasks performed by contractors, maintenance technicians, and tradespeople.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is commonly used in wood framing, deck construction, equipment mounting, and general structural connections where a flush or low-profile bolt head is required on the finished face. The square neck seats into pre-drilled square holes or bites into wood to resist turning, making it straightforward to install with a single wrench or socket on the nut side. It is appropriate for indoor and outdoor applications where zinc plating provides basic corrosion resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSquare neck prevents bolt rotation during nut tightening without a second wrench\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread form for broad nut and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e8.5-inch length under head suits deep through-bolt assemblies\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel meets ASTM A307 standard for general structural fastening\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion and oxidation resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose 1\/2-13 UNC carriage bolt for use with standard 1\/2-inch nuts, washers, and hardware in wood and light structural applications conforming to inch-standard dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, ironworkers, or general tradespeople using standard hand tools or impact drivers.
