A Carriage Bolt, also known as a Round Head Square Neck Bolt, is a fastener commonly used in wood-to-wood and wood-to-metal fastening applications. It features a smooth, dome-shaped round head and a square neck just beneath the head. The square neck locks into the material when tightened, preventing the bolt from rotating during installation. This makes it ideal for applications requiring tamper resistance and a clean, smooth head finish.
