A carriage bolt has a square neck with a round head and is most often used to connect pieces of lumber together. Because the neck and head are different shapes, they work together to provide a better anchor once the bolt is threaded into the wood. They are frequently used as a fastener for lumber at construction sites.

Carriage bolts are commonly used to connect building materials and hold them in place. These bolts are called for when a job requires extra durability and strength, because they are more heavy duty than screws due to their increased thickness and size.

Carriage bolt distributors offer a complete supply of bolts that are ideal for wood working purposes. Use the resources below when you need to:

1. Buy carriage bolts for the contracting jobs your company has landed;

2. Stock brass carriage bolts for your retail location;

3. Request a special order from a carriage bolt manufacturer;

4. Order industrial carriage bolts for larger projects.
