The square neck seats into the workpiece to prevent rotation during installation, eliminating the need for a wrench on the bolt head. Compliant with ASTM A307, this fastener is suited for general-purpose structural and mechanical assembly applications. The zinc coating provides basic corrosion resistance for indoor and sheltered outdoor use.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is used in wood-to-wood and wood-to-metal connections across residential construction, light commercial framing, equipment assembly, and general fabrication. The 3\/8-16 thread is a common size for lumber connections, fence construction, deck building, and bracket mounting. Tradespeople and contractors use this bolt when a smooth, round head finish is required on the visible face of the assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread for broad compatibility with standard nuts and hardware\u003c\/li\u003e\n\u003cli\u003e3-inch length under head for moderate-depth through-fastening applications\u003c\/li\u003e\n\u003cli\u003eSquare neck design locks into material to resist rotation during tightening\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standards\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish for basic corrosion resistance in sheltered environments\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 hex nuts and washers in wood, light steel, and composite assemblies per inch-standard fastener specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, ironworkers, or general contractors using a standard socket or wrench on the nut side only.
