What Is a Hex Nut?

A Hex Nut is a common type of fastener that has a threaded hole. It is almost always used in conjunction with a mating bolt to fasten two or more parts together. The bolt and nut are held together by friction between the threads and slight stretching or compression of the parts.
These nuts are available in several sizes and materials, and can be used for many different applications. They are convenient to use and can be easily tightened, as their threads are accessible from all directions. Although hex nuts are widely used, certain projects may require a different type of nut. For these projects, you can order specialty nuts online or from a hardware store.
Hex nuts are available in a variety of sizes. Typically, they range from 1/4" through 2 1/2" in diameter. In addition, hex nuts can be purchased in metric sizes as well. They can also be made in different thread profiles, which can be important depending on the application. Hex nuts are designed to provide greater strength than their bolt counterparts. Using a weaker nut with a stronger bolt can cause the fastener to fail.
The hex nut is one of the most common types of nuts on the market. They are commonly used in wood-to-wood and metal-to-metal applications to keep the components in place and prevent any movement. For general applications, you should choose a grade 5 medium carbon steel hex nut.
