In engineering, carpentry, and construction, a nail refers to a pointed, hard metal (usually steel) used to hold things such as wood in place. Hammers drive nails into objects, and there are also electric nail guns and gas nail guns. The nails are able to stabilize objects because they are hooked on them by their own deformation and by friction.
Nails come in different shapes due to their many uses. The most common nails are called "wire nails", and other common nail names are pins, thumbtacks or brad nails. Nails are widely used and used in many scenarios. Generally, rivets for aircraft carriers are more expensive, and ordinary nails are cheaper.
