Common nails are used for general construction purposes. The nails have a thick head so that they can be driven into hard objects and materials. They come in various lengths and sizes, starting from 2d going up till 60d. Normally, because they are common nails, they are not made of stainless steel because stainless steel nails are more expensive than standard iron nails. Since common nails are made of iron, they should be kept in an anti-rust atmosphere.
Rust is formed when a particular material reacts with oxygen, and the effect of this reaction is the flaking of the metal, a process better known as rusting. Water plays an important part in causing rust on metal and iron objects. The best policy is to prevent rust rather than trying to remove it afterwards. Iron objects, such as common nails tend to rust quickly if no precautions are taken to prevent it.
As mentioned before water accelerates the process of rusting thus is the number one enemy to common nails. When you are storing your unused common nails, you have to store them in a place where no water will come in contact with them. Make sure that the storage you are using does not have a leaky ceiling, where rain can seep in and rust the nails easily. It is advisable to store your nails, and similar objects, in a water tight plastic or wooden container to hinder any water from starting the process of oxidization on your common nails.
Humidity is also a killer for iron objects and can be present in any area of your home or store. Plan a thorough check whether your storage room is humid free because, although you may at first not see any rust on your nails, it’s just a matter of time till they are ruined. If you store your common nails on the floor it is a good idea to put them on a mat instead of putting them directly on the floor to avoid any cool moist from damaging them.
Paint or Wax
A method used to try to resist rust is to paint or apply wax (which doesn’t contain water) to the nails. This method is usually used for metal tools rather than simple nails but it really does work, so if you have the time you could paint or apply wax to your common nails.
Dust is an effective magnet for humidity so if you want to prevent any rusting on your nails put them in a dust free environment and in a plastic or wooden box. It is better to store your common nails in a wooden box because wood has a tendency to block humidity molecules from entering and obviously doesn’t allow dust to enter either.
If you think that your storage room may contain humidity, try using a dehumidifier to clear the air and protect your metal objects, including the common nails. It is also advisable not to use cardboard boxes when storing your nails since it does not offer any protection against any harmful substance or humidity present in the air.
