### 1. What are carriage bolts?

Carriage bolts, also known as coach bolts or round head square neck bolts, are specialized fasteners used to secure metal to wood. They feature a smooth, dome-shaped head and a square section under the head to prevent it from turning when tightened. Carriage bolts typically have a square neck beneath the head that grips into the wood to prevent it from rotating during installation.

### 2. How do you use carriage bolts?

When using carriage bolts, follow these steps for successful installation:

1. **Drill a pilot hole:** Begin by drilling a hole in the wood slightly smaller than the diameter of the carriage bolt. This will prevent the wood from splitting when the bolt is inserted.

2. **Insert the bolt:** Place the carriage bolt through the hole with the smooth, rounded head on the side where a finished look is desired.

3. **Add a washer and nut:** On the other side of the wood, slide a washer over the bolt, followed by a nut. Tighten the nut until it is secure but not over-tightened, as this could strip the threads.

4. **Secure in place:** Use a wrench to tighten the nut further if needed, ensuring the carriage bolt is secure in the wood.

5. **Cut off any excess:** If the bolt sticks out from the nut, use a hacksaw to cut off any excess length. This will give a clean, finished appearance to the bolt.

By following these steps, you can successfully use carriage bolts to secure metal to wood in various applications, such as building projects, furniture assembly, or outdoor structures.
