Nut and bolt Trick

The "nut & bolt trick" typically refers to a simple yet effective method used to solve a common problem encountered when dealing with nuts and bolts that are difficult to separate due to rust, corrosion, or overtightening. Here's how it works:

Apply Lubricant: Start by spraying or applying a lubricant, such as penetrating oil or WD-40, generously around the stuck nut and bolt. Allow the lubricant to penetrate the threads and loosen any rust or corrosion that may be causing the issue.

Tap Gently: Once the lubricant has had time to work its way into the threads, gently tap the head of the bolt with a hammer. The vibrations from tapping can help to further loosen the bond between the nut and bolt.

Use Heat: If the nut and bolt remain stuck after applying lubricant and tapping, you can try applying heat to the area. Use a heat gun or propane torch to heat the nut directly for a few minutes. The expansion caused by the heat can help to break the bond between the nut and bolt.

Use Vice Grips: If the above methods fail, you can try using a pair of vice grips or locking pliers to grip onto the head of the bolt firmly while using a wrench to turn the nut counterclockwise. The additional grip provided by the vice grips can sometimes provide the extra leverage needed to break the nut free.

Cutting: As a last resort, if all else fails, you may need to cut through the bolt with a hacksaw or angle grinder. Be sure to wear appropriate safety gear, such as gloves and eye protection, when cutting through metal.

By following these steps, you can often successfully separate a stuck nut and bolt using the "nut & bolt trick" without damaging the surrounding materials.
