Durable, Corrosion-Resistant Fasteners for Secure Connections in Challenging Environments

Enhance your woodworking, construction, and outdoor projects with our premium 3/8"-16 Carriage Bolts, crafted from A307 Grade A steel and Hot Dipped Galvanized (HDG) for improved corrosion resistance. These bolts provide dependable strength, making them ideal for a range of applications where durability and reliability are essential.

Carriage bolts feature a smooth, domed head with a square neck beneath. This design self-locks into a pre-drilled hole, preventing rotation as you tighten the nut. Perfect for wood-to-wood, wood-to-metal, and some metal-to-metal applications, carriage bolts are commonly used in fencing, decking, furniture assembly, and projects requiring tamper-resistant connections.

Undersized Options for HDG Fasteners

Certain bolt lengths may be undersized to compensate for the zinc coating added during galvanizing. Because the zinc layer slightly increases the thread diameter, starting with an undersized thread ensures the final size after galvanizing matches standard dimensions. Not all lengths are undersized??please refer to the variation details for which lengths have this feature.

Compensation for Zinc Buildup: Undersizing accounts for the added zinc thickness, ensuring a correct post-galvanizing fit.
Smooth Nut Installation: Undersized threads prevent overly tight fits after galvanizing, making nut installation easier.
Design Consideration: Specifying undersized HDG fasteners ensures proper functionality and ease of assembly in your project.

Key Benefits of Our HDG Carriage Bolts

Corrosion Resistance: Hot Dipped Galvanizing provides excellent protection against rust, pitting, and corrosion, ideal for outdoor and industrial environments.
Self-Locking Square Neck: The square neck design prevents the bolt from spinning as the nut is tightened, ensuring a stable connection.
Flush, Clean Appearance: The domed head sits flush with the surface, offering a neat, professional look.
Easy Installation: Just tap the bolt into place and tighten the nut??no twisting of the bolt head required.
Tamper-Resistant: The smooth head allows removal only from the nut side, enhancing security.
