Penetrating Oil:
- Apply a penetrating oil like WD-40 or Liquid Wrench to the rusted bolt and let it sit for several hours or overnight. The oil helps to dissolve the rust and lubricate the threads, making it easier to turn.
Heat Application:
- Use a heat gun or a propane torch to heat the bolt. Heating can expand the metal, loosen the rust, and make the bolt easier to turn. Avoid using too much heat as it can damage the surrounding material or the bolt itself.
Tapping and Impact:
- Use a hammer or rubber mallet to tap the head of the bolt in a clockwise direction while applying pressure with a wrench. The tapping helps to break the rust's grip and loosens the bolt.
Rust Dissolver:
- Use a commercial rust dissolver or a vinegar and baking soda solution. Apply the dissolver to the rusted bolt and let it sit according to the recommended time. Rinse the area with water and try turning the bolt.
Leverage:
- If possible, use a long wrench or a breaker bar to provide additional leverage while turning the bolt. This can help to overcome the resistance caused by the rust.
Locking Pliers:
- Use locking pliers to grip the head of a bolt or nut if there's no space for a wrench. These pliers can provide a strong grip to turn the bolt.
Left-Hand Drill Bit:
- In extreme cases, a left-hand drill bit can be used to extract a broken or severely rusted bolt. Drill a small pilot hole in a counterclockwise direction, and the bit should engage with the bolt's threads and loosen the bolt.
Note:
- Always wear protective gear, including safety glasses and gloves, when working with tools.
- If the bolt is significantly rusted or damaged, it may be best to replace it rather than trying to remove it.
- If you encounter significant difficulty, consult with a professional to avoid causing damage or injury.
