The square neck design locks the bolt in place against the mating surface during installation, preventing rotation as the nut is tightened. This fastener meets ASTM A307 standards and uses a Unified National Coarse (UNC) thread form. It is a general-purpose structural bolt suited for wood-to-wood and wood-to-metal connections commonly found in construction, equipment mounting, and maintenance applications across mechanical and trade work.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is used in a wide range of light structural and general fastening applications, including framing, equipment bases, and utility installations. The zinc plating provides basic corrosion resistance suitable for dry or mildly exposed indoor environments. Tradespeople in HVAC, plumbing, electrical, and general construction rely on this fastener type when a flush, round-head profile and anti-rotation square neck are required. Each order is fulfilled in a minimum quantity of 50 pieces, making it practical for stocking in service vans or shop bins.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size for broad hardware compatibility\u003c\/li\u003e\n\u003cli\u003e5-inch length under head for deeper material stack applications\u003c\/li\u003e\n\u003cli\u003eSquare neck prevents bolt rotation during nut tightening without requiring a wrench on the head\u003c\/li\u003e\n\u003cli\u003eGrade A steel construction meets ASTM A307 fastener standard\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides corrosion resistance in dry and lightly exposed environments\u003c\/li\u003e\n\u003cli\u003eInch measurement system with length measured under the head\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-13 UNC carriage bolt suitable for use with any standard 1\/2-13 hex nut and compatible with wood, metal, and composite substrate applications requiring an ASTM A307 Grade A fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by inserting the bolt through a pre-drilled hole and seating the square neck into the substrate to prevent spinning.
