The square neck under the dome head locks into wood or soft material to prevent rotation during tightening. Manufactured from Grade 1006-1050 steel with a galvanized zinc-plated finish, this bolt resists corrosion in exposed or moisture-prone environments. It is fully threaded along its entire 4-inch shank, conforming to ASME B18.5 standards. Tradespeople working in wood framing, equipment mounting, and structural assembly will find this a reliable standard-size fastener.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for residential and light commercial applications where a flush, smooth dome head is required on the show face of an assembly. Common uses include deck and fence construction, equipment mounting to wood substrates, and general structural connections. The fully threaded shank provides maximum thread engagement when used with a standard 1\/4-20 hex nut and washer. Sold individually per package, with a minimum order quantity of 100 units, making it practical for stocking or bulk project use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread size with full threading along the 4-inch shank\u003c\/li\u003e\n  \u003cli\u003eSquare neck under the dome head prevents bolt rotation during installation\u003c\/li\u003e\n  \u003cli\u003eGrade 1006-1050 steel construction for reliable tensile performance in general-duty applications\u003c\/li\u003e\n  \u003cli\u003eGalvanized zinc-plated finish provides corrosion resistance in outdoor or damp environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.5 fastener standard\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; length specified as length under head\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC carriage bolt for use with compatible 1\/4-20 hex nuts, wing nuts, and washers in wood and light structural assemblies per ASME B18.5 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by inserting the bolt through a pre-drilled hole sized to allow the square neck to seat flush and grip the material surface, preventing spin. A standard open-end or socket wrench is used to tighten the mating nut from the opposite side. Always verify hole diameter is matched to the bolt shank to ensure the square neck seats correctly.
