It features a 3\/8-16 UNC thread size with a 3-1\/2 inch length under head and a square neck that locks into material surfaces to prevent rotation during installation. Manufactured from Grade 1006-1050 steel with a galvanized zinc-plated finish, it offers corrosion resistance suitable for both indoor and outdoor use. This bolt conforms to ASME B18.5 standards and is measured using the inch system. Tradespeople and contractors working in structural, mechanical, or general construction applications will find this bolt well-suited to high-volume fastening tasks.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is commonly used in wood framing, deck construction, equipment mounting, and general structural assembly where a tamper-resistant, self-locking fastener is required. The square neck seats into pre-drilled square or round holes in wood to resist spinning, eliminating the need for a wrench on the bolt head during tightening. It is appropriate for residential and light commercial construction projects and is typically installed by carpenters, general contractors, electricians, and plumbers when anchoring panels, junction boxes, brackets, or structural members.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC fully threaded design for maximum thread engagement along the full shank length\u003c\/li\u003e\n\u003cli\u003e3-1\/2 inch length under head accommodates thicker material stacks\u003c\/li\u003e\n\u003cli\u003eSquare neck prevents bolt rotation during nut tightening without requiring a tool on the head\u003c\/li\u003e\n\u003cli\u003eGrade 1006-1050 steel construction provides reliable tensile strength for general-purpose fastening\u003c\/li\u003e\n\u003cli\u003eGalvanized zinc-plated finish delivers corrosion resistance for exposed or outdoor installations\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.5 fastener standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC carriage bolt for use with 3\/8-16 nuts and washers in general construction, structural, and mechanical fastening applications conforming to ASME B18.5.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, contractors, or trade professionals using a standard wrench or socket on the nut side while the square neck seats into the material to prevent bolt rotation. Pre-drill the appropriate hole diameter to allow the square neck to seat flush without splitting the material. Always ensure the mating nut and washer match the 3\/8-16 UNC thread specification.
