Carriage Bolts – Smooth, Secure Fastening for Wood & Metal
 
Our Carriage Bolts feature a round, domed head with a square neck that locks into place during installation—perfect for fastening wood to wood or wood to metal where a clean, tamper-resistant finish is needed. The square shoulder prevents the bolt from turning when tightened, making these bolts ideal for decking, fencing, framing, and machinery. Available in zinc-plated and 304 stainless steel for indoor or outdoor use.
