Built to ASME B18.5 standards, this bolt features a 5\/16-18 UNC thread and measures 5-1\/2 inches in length under the head. The square neck seats into the substrate to prevent rotation during tightening, eliminating the need for a wrench on the bolt head. Constructed from Grade 1006-1050 steel with a galvanized zinc-plated finish, it provides corrosion resistance suitable for both indoor and outdoor installations.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for wood-to-wood, wood-to-metal, and general structural assemblies commonly found in construction, fencing, decking, equipment mounting, and utility framing. The 5\/16-18 UNC thread size is a standard inch-series specification widely used across residential and light commercial projects. Tradespeople, contractors, and maintenance crews working on structural connections will find this bolt appropriate for through-bolt applications where a nut and washer are used on the opposing side.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC fully threaded shank for maximum thread engagement along the full bolt length\u003c\/li\u003e\n  \u003cli\u003e5-1\/2 inch length under head accommodates thicker material stacks and spacer assemblies\u003c\/li\u003e\n  \u003cli\u003eSquare neck design locks into substrate to resist rotation during nut tightening\u003c\/li\u003e\n  \u003cli\u003eGalvanized zinc-plated finish provides corrosion resistance for indoor and outdoor use\u003c\/li\u003e\n  \u003cli\u003eGrade 1006-1050 steel construction meets ASME B18.5 fastener standards\u003c\/li\u003e\n  \u003cli\u003eInch system of measurement for compatibility with standard SAE tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series carriage bolt for use with 5\/16-18 UNC nuts and washers in wood, composite, and light structural metal assemblies per ASME B18.5.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert the bolt through a pre-drilled hole sized to allow the square neck to seat flush and prevent spin.
