What is a hex nut?

A hex nut is a type of fastener with a threaded hole that has six sides (hexagonal shape). It is designed to be used with a corresponding bolt or screw to fasten objects together.

They come in various materials and finishes, including steel, stainless steel, brass, and more, depending on the specific requirements of the application.
