Use a Bernzomatic torch and a little elbow grease to loosen frozen, rusted or stubborn nuts and bolts.
- For stubborn bolts, heat the bolt, then move the flame away and apply WD-40 against the heated bolt threads. The melting wax pulls itself into the threads to create a slippery surface.
- Keep open flames away from fuel and brake lines, rubber fittings and other flammable parts and materials.
- Read our General Safety Precautions before starting your project.
- Read the instructions that come with your torch before beginning your project
- Check thoroughly to ensure there are no flammable materials such as plastic or fabric in close proximity to the bolt you’ll be heating.
- Apply penetrating oil to the bolt and give it a few minutes to sink in. Use a rag to soak up and remove any residual oil.
- Turn on your torch and aim the flame directly at the bolt head. Move the flame in a circle around the bolt for 30 seconds.
- Use a socket wrench to rock the bolt back and forth until it loosens enough to be removed. The bolt is stubborn, repeat steps 2 and 3.
