1. Lubricate the Bolt:
- Apply a penetrating lubricant, such as WD-40, Liquid Wrench, or a similar product, to the rusty bolt. Allow it to sit for a while to penetrate the threads.
2. Use Heat:
- Heat the nut or bolt with a heat gun or propane torch. Be cautious not to overheat the metal as it may damage the threads. Once heated, try loosening the bolt.
3. Tap the Bolt:
- Gently tap the bolt head with a hammer to break the rust bond. Tap the bolt in the direction it needs to turn to loosen it.
4. Use a Wrench with Leverage:
- If you can, use a wrench with a long handle to increase leverage and more easily turn the rusty bolt.
5. Use a Screwdriver:
- Insert a flathead screwdriver into the bolt head slot and use a wrench or hammer to turn the screwdriver, which in turn will loosen the bolt.
6. Pliers:
- In some cases, pliers may provide a good grip on the bolt head, allowing you to turn it.
7. Remove Nut or Bolt Head:
- If you can't loosen the bolt, and it's exposed on one side, you can try to remove the nut or bolt head with the appropriate tool.
8. Wire Brush:
- Clean the bolt and surrounding area with a wire brush to remove loose rust and debris.
9. Vise Grip:
- If the bolt is exposed and accessible, use a locking pliers (Vise Grip) to firmly grasp the bolt and turn it.
10. Angle Grinder:
- If all else fails and you have access to an angle grinder, you may need to cut the bolt off if it's badly corroded.
Remember to safety precautions when working with lubricants, heat, or power tools. If the bolt is severely rusted or damaged, you may need to seek professional assistance or replace it altogether.
