Nails are often coated with vinyl or phosphate to make them easier to drive into wood. The friction caused by driving the nail into the wood melts the coating, lubricating the nail. This coating also makes the nail more resistant to corrosion and harder to pull out. Some nails are also coated with lacquer or varnish, and some are 'cement-coated' to make them weather and water-resistant.

Nails are coated with vinyl to make them easy to drive
Nails are commonly coated with vinyl to make them easy to drive. When a nail is driven into wood, the friction increases the surface temperature of the nail, melting the coating and lubricating the nail. When the nail stops moving, the vinyl cools and improves the withdrawal resistance.
The coating is not always obvious, but it can be revealed by scraping the nail with a sharp razor. This coating is similar to a thin layer of lacquer or varnish. Nails are also coated with phosphate to increase their holding power and provide some resistance to corrosion.
Some nails are coated with cement to make them resistant to weather and water. These are usually used for exterior applications. Other coated nails may be more resistant to loosening and can be used indoors.
It is important to note that not all nails are coated. For example, galvanised nails do not have a coating. Additionally, some imported nails may have a coating that looks like vinyl, but it is not true vinyl and is simply a decorative coating to conceal corrosion during shipping.

The friction heat melts the coating, making it more difficult to pull out
Nails are commonly coated with vinyl to make them easy to drive. When a nail is driven into wood, the surface temperature of the nail is increased by friction. This friction is just enough to melt the coating and lubricate the nail. When the nail stops moving, the vinyl cools and improves the withdrawal resistance.
Some nails are cement-coated to make them resistant to weather and water, and these are designed for exterior applications. Other coated nails may be more resistant to loosening and can be used indoors.

Cement-coated nails are designed to be resistant to weather and water
Nails are commonly coated with vinyl to make them easy to drive. When a nail is driven into wood, the surface temperature of the nail is increased by the friction. This friction is just enough to melt the coating and lubricate the nail. When the nail stops moving, the vinyl cools and improves the withdrawal resistance.
Nails are also commonly coated with phosphate to increase their holding power. This coating also provides some modest resistance to corrosion.

This friction is just enough to melt the coating and lubricate the nail. When the nail stops moving, the vinyl cools and improves the withdrawal resistance. Some coated nails are more resistant to loosening. This is because the friction heat melts the coating, making the nail more difficult to pull out. On some nails, the coating is obvious, but on others, it is less visible. However, it can be seen when scraped with a sharp razor. These coatings are sometimes called "cement-coated" and are designed to be resistant to weather and water. They are more commonly used for exterior applications than interior-rated nails.
