Durable, Corrosion-Resistant Fasteners for Secure and Reliable Connections

Enhance your woodworking, construction, and outdoor projects with our premium 1/4"-20 Carriage Bolts, crafted from A307 Grade A steel and coated with Zinc Yellow CR+6. These bolts offer dependable strength and corrosion resistance, making them perfect for a variety of applications where durability and reliability are essential.

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

Key Benefits of Our Zinc Yellow CR+6 Carriage Bolts

  • Enhanced Corrosion Resistance: Zinc Yellow CR+6 coating provides superior protection against rust, pitting, and corrosion in outdoor and industrial environments.
  • Self-Locking Square Neck: The square neck design ensures the bolt remains stationary as the nut is tightened, providing a secure and stable connection.
  • Flush, Clean Appearance: The domed head sits flush with the surface, reducing snagging and offering a professional, polished look.
  • Easy Installation: Simply tap the bolt into place and tighten the nut from the opposite side—no twisting of the bolt head required.
  • Tamper-Resistant: The smooth head design allows removal only from the nut side, enhancing security and preventing unauthorized adjustments.
