Hardware Nuts like hex nuts and flange nuts are common items we see all around us. They are tiny rounded hardware with threaded holes, used with a screw to hold multiple parts of a device in place. We use nuts in devices, machines, appliances, and so on to either hold parts together, tighten an appliance to a surface, and hold so many other things to a spot.

Nuts work with screws in performing these functions listed above. Now we know what nuts are, have you ever imagined what they actually look like and how they vary in sizes and shapes. Yes, some nuts are not just rounded, they have sides and edges and this determines the type of nut it is. For this article, we would be dwelling on a particular type of nut called a Hex Nut.

Hex nuts - comprehensive overview

What are hex nuts?

They are nuts that have six sides. By way of definition, Hex nuts are six-sided internally threaded fasteners mated with bolts, studs, screws, and other externally threaded products. Hex in this context is a shorter version of the hexagon (a shape with six sides). They are therefore called Hex Nuts because they are made up of six sides.

  • Hex finish nuts
  • Hex machine nuts
  • Heavy hex nuts
  • Hex jam nuts

Finish nuts are of standard thickness. They are neither as thick as Heavy Hex Nuts nor as light as Jam Nuts. We use them to fasten Hex cap screw, bolt, or socket and are the most commonly used Hex Nut.

How to fasten a hex nut

Learning how to use a Hex Nut depends on the situation where it is being used. We hold these nuts in place using fasteners like bolts and screws with the help of a spanner. They however go majorly with bolt fasteners. We can also fasten them with nuts too (as in the case of two Jam Nuts). See various types of fasteners HERE.
