What is a Hexagonal Nut?

A six-sided hexagonal nut is a kind of metallic fastener. Because it appears to be the simplest form to grip, the majority of nuts are carved in a hexagonal structure. Nuts are usually solely utilized to secure a bolt to another component in any manner. Hexagon nuts are used in a number of applications. Furniture, domestic appliances, construction structures, children’s toys, vehicles, as well as other items contain them. 

If you’re wondering of many shapes why nuts are mostly of hexagonal form, here’s the reason.

Reasons for the hexagonal shape of nuts:

There are six parallels in the nuts. The hexagonal form was chosen because, with six sides, a fastener may be turned only one-sixth of the way to reach the next parallel. 

A square fastener, for example, must be turned 90 degrees to reach the flat parallel, but hexagonal nuts only need to be rotated 30 degrees to pass the next flat parallel. Because they have six parallels, hexagonal nuts are simpler to spin than other forms of fastening.
