The term "fastener" is a broad term encompassing a wide range of tools. These tools include screws, bolts, nuts, etc., and they all share a common goal: to enable objects to adhere mechanically. In short, fasteners help hold objects in place or mechanically fasten them together.

You might argue that glue can effectively perform this function. If glue isn't an example of a fastener, then what is a fastener? This prompts us to expand on the initial definition. Hardware fasteners are those that help mechanically fasten objects together.

Fasteners have a broad classification. They are divided into permanent and non-permanent fasteners. Generally, fasteners are considered to form non-permanent joints. That is, you should be able to separate two components connected by the fastener. When the pieces come apart, they must not suffer any form of damage. An exception to this rule is the rivet, which is a permanent fastener.

The fact that most fasteners form non-permanent joints does not mean the joint is weak. Using properly shaped fasteners will allow you to reliably hold your items. This way, you can be certain that your object can withstand high levels of stress. They are versatile and can be used for various types of joints.
