This partially threaded bolt features a ribbed neck that bites into the mating material to prevent spinning during installation without requiring a tool on the bolt head. Manufactured to Grade 5 steel and finished with zinc trivalent chromate, it provides a solid corrosion-resistant fastener for both indoor and outdoor assemblies. Thread length is 0.75 inches. Overall length under head is 1.5 inches.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for light structural and mechanical assemblies in residential construction, light commercial work, and equipment fabrication. Typical applications include wood-to-wood connections, bracket mounting, and general hardware assembly where a flush or low-profile bolt head is needed. The partially threaded shank allows the unthreaded section to bear load in the joint without thread interference. Installation is straightforward and does not require access to the bolt head once seated.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRibbed neck resists rotation during nut tightening without a wrench on the bolt head\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 strength standards\u003c\/li\u003e\n  \u003cli\u003eZinc trivalent chromate finish provides corrosion resistance for indoor and outdoor use\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank with 0.75 inches of thread length\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread size for broad compatibility with standard nuts and hardware\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; length measured under head at 1.5 inches\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 hex nuts, wing nuts, and flat washers in general fastening applications conforming to SAE J429 requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by hand or with a hammer to seat the ribbed neck flush into the mating substrate, followed by tightening the nut with a standard wrench or socket.
