Carriage bolts are designed to fasten a wooden face to either a wood or metal frame. Its flat head is designed to eliminate the need for a washer and provide a semi-flush finish to applications. The square underside of the head is self-locking to eliminate spinning and the need for a driving tool. The galvanized finish provides optimal rust prevention but can be chalky in appearance.

  • Design: Carriage bolts have a smooth, rounded head and a square neck, which prevents them from turning when the nut is tightened.
  • Thread Pitch: Coarse threads (UNC) are commonly used, providing a stronger hold compared to fine threads (UNF)
  • Commonly used for securing wood to wood, wood to metal, and metal to metal
