Carriage Bolts: The Workhorses of Wood-to-Metal Connections
Carriage bolts, often called "coach bolts," are specialized fasteners designed for wood-to-metal applications. Their rounded, unthreaded head and square neck make them ideal for applications where a flush finish is desired or where the bolt needs to be driven through a pre-drilled hole in wood.
Carriage bolts have evolved from their early blacksmith-forged iterations to modern precision-machined bolts made from various metals like steel, stainless steel, and brass. This evolution has brought about improved strength, corrosion resistance, and dimensional accuracy.
Key features that distinguish carriage bolts include their unique head design, available in round, oval, and hexagonal shapes. They are also categorized by their material, finish (plain, galvanized, or plated), and thread type (coarse or fine).
The carriage bolt market continues to grow, driven by their versatility in furniture making, construction, and industrial applications. Advances in material science and manufacturing techniques are leading to even stronger and more corrosion-resistant bolts, ensuring their continued relevance in the future.
