To remove a snapped bolt, you can try the following steps:
1. **Assess the Situation**: Determine how much of the bolt is still accessible and how much is broken off.
2. **Apply Lubricant**: Use a penetrating oil like WD-40 to help loosen the bolt. Let it sit for a few minutes to allow the oil to work its way into the threads.
3. **Use Pliers or Vice Grips**: If there is enough of the bolt exposed, try using locking pliers or vice grips to grip the bolt securely and turn it counterclockwise to remove it.
4. **Heat**: If the bolt is stuck due to rust or corrosion, you can use a heat source like a propane torch to heat the area around the bolt. This can expand the metal and make it easier to turn the bolt out.
5. **Drilling**: If the above methods do not work, you may need to drill out the bolt. Use a drill bit slightly smaller than the bolt diameter and drill into the center of the bolt. Be careful not to damage the surrounding material.
6. **Extractors**: After drilling, you can use a screw extractor to remove the remaining bolt. These tools are designed to grip onto the bolt and allow you to turn it out.
Remember to take your time and work carefully to avoid causing further damage to the surrounding material. If you are unsure or uncomfortable attempting this yourself, it may be best to seek the help of a professional.
