A Carriage Bolt, also known as a Round Head Square Neck Bolt, features a smooth, domed head and a square neck beneath the head that locks into place when inserted into a square hole or wood. This design prevents the bolt from turning during tightening, making it ideal for wood-to-wood or wood-to-metal applications. Carriage bolts are widely used in construction, fencing, furniture assembly, and automotive bodywork where a smooth, finished appearance is desired.
