A hexagon nut is a type of fastener characterized by its six flat sides, which allow it to be easily grasped and turned with a suitable tool, such as a wrench. The term "hexagon" specifically refers to the six-sided shape, derived from the Greek prefix "hex," meaning six. This design provides a good balance of strength and ease of use in fastening applications. Additionally, the geometry of the hexagon allows for an even distribution of force when the nut is tightened, making it a common choice in various mechanical and construction settings.

Other shapes tend to have either fewer or more sides, such as square nuts with four sides, pentagonal nuts with five sides, or octagonal nuts with eight sides, further emphasizing the significance of the correct identification of the hexagon's properties.
