1. Use the right tool
Choose the right tool: Use a hex wrench or socket wrench that matches the size of the bolt head. If the bolt head is worn or deformed, you may need to use a smaller tool, or use a tool with a rubber pad to increase friction.
Use pliers or a wrench: If the bolt head is worn, you can try to use pliers or a wrench to clamp the bolt head and then turn it counterclockwise to loosen the bolt.
2. Apply penetrating oil
Use penetrating oil: Apply a few drops of penetrating oil, such as WD-40 or PB Blaster, to the bolt and let it penetrate into the threads. Wait for a while for the oil to soften the rust and dirt on the threads.
3. Tap the bolt
Gently tap the bolt: Use a hammer to gently tap the bolt head to help break up the adhesion of rust and dirt.
4. Use a heat source
Heat the bolt: If the bolt is still difficult to loosen, you can use a hair dryer or blowtorch to heat the bolt. Thermal expansion may make the bolt easier to loosen.
5. Turn counterclockwise
Turn counterclockwise: Use the tool to turn the bolt counterclockwise until it starts to loosen.
6. Use a bolt extractor
Use a bolt extractor: If the bolt head has been severely worn or deformed, you may need to use a bolt extractor. These tools are designed to bite into the damaged bolt and turn it counterclockwise to remove it.
Precautions
Safety first: During the operation, always wear appropriate protective gear, such as non-slip gloves and goggles.
Avoid damage: When trying to remove the bolt, try to avoid damage to surrounding parts.
