How to Remove Rust from Bolts

Rust from bolts and nuts are never welcome. As a matter of fact, rusted equipment may cause serious issues and accidents. Nuts and bolts should be treated with rust-resistant compounds as most of these parts are prone to rust. Rusting is a good example of deterioration. The problem is not all kinds of rust can be detected by the naked eye. But when rust does accumulate then other parts and components are affecting, thereby leading to malfunctions. Eventually, the machine will fail.

Rust occurs when iron oxides form in metals and its alloys. It is a type of corrosion that forms when water combines with oxygen, thus causing the stiff and non-reactive coating on the surface of the metal. These rusted parts tend to flake away, which causes more surfaces to be exposed to the elements. Rusting doesn’t stop up until the metal is dissolved. This is why rust in fasteners, bolts, screws, and nuts should never be taken for granted.

How to Remove Rusted Parts

If the screws, bolts, and nuts of the machine are exposed to water and moisture for a considerable period of time, they’ll rust quickly. This is true among outdoor machines, home appliances parts, and automobile components. Moisture degrades the strength of these parts and removing the rusted ones is quite difficult. Here are some tips to make it easier to do so:

1. Lubrication

There are industrial and commercial lubricants that can reach the inner threads, especially the ones that are difficult to grasp. Apply lubricant to the screws, nuts, and bolts first and then use a hammer to tap their heads. Doing so allows the lubricant to penetrate deep within, thus allowing the bolts to loosen up and be removed.

2. Cutting

There are times that the fastener is severely rusted that it cannot be saved anymore. For these cases, cutting it is the only option. Doing so will make the fastener unusable and that means it has to be replaced. For that, you’ll need to contact a Wisconsin bolt and nut supply company for a replacement. To cut the fastener, a nut splitter, industrial shears, and cut-off wheel may be used. A vise-grip may also be used to clamp the bolt to twist its head off.

3. Torching

Applying heat is also a good way to remove rusted nuts and bolts. Heat allows the metal to expand, which makes them a bit lose. However, be sure that you practice caution when using a torch to remove rusted bolts, especially if you applied some lubricant. Many lubricants are flammable.

Other Way to Remove Rust

Replacing rusted fasteners is the common practice although there are nuts and bolts that are hard to replace because they come from older machines. For these cases, you have no choice but to manually get rid of the rust from the parts after they have been removed from the machine.

To remove rust from bolts, nuts, and screws, the first step is to clean them. You may also apply some hydrogen peroxide or rust cleaner. Sanding and repainting will also help.
