Fasteners are vital components that join two or more objects together. They are used in various industries, including automotive, construction, electronics, aerospace, and more. There are many different types of fasteners available in the market, each having its unique features and characteristics. In this article, we will discuss the five basic types of fasteners that you should know about.


1. Bolts

Bolts are a type of fastener that has external threads and requires a nut to secure objects in place. They are commonly used in construction, automotive, and aerospace industries. Bolts come in various materials, including steel, stainless steel, brass, and aluminum. They are available in different sizes, thread pitches, and grades, making them versatile and suitable for different applications.


2. Screws

Screws are one of the most common types of fasteners used in household and industrial applications. They are similar to bolts but have internal threads that engage with the threads of the receiving object. Screws are available in various head types, including flat, oval, round, pan, and hex, and come in different materials, including steel, stainless steel, brass, and nylon.


3. Nuts

Nuts are a type of fastener that is used along with bolts and screws to secure objects in place. They have internal threads that engage with the external threads of bolts and screws. Nuts come in various shapes, including hexagonal, square, wing, and cap, and are available in different materials, including steel, brass, and nylon.


4. Washers

Washers are flat or slightly curved discs that are used in conjunction with bolts, screws, and nuts to distribute the load over a bigger surface area. They come in various materials, including steel, stainless steel, bronze, brass, and nylon. Washers are available in different shapes, including flat, split, and spring, and are used in various applications, including plumbing, automotive, and construction.


5. Rivets

Rivets are a type of fastener that is used when objects need to be permanently joined together. They are made from a variety of materials, including steel, aluminum, brass, and copper, and come in various sizes and shapes. Rivets are commonly used in automotive, aerospace, and construction industries, where a strong and permanent joint is necessary.


In conclusion, fasteners are essential components that hold different objects together. The five basic types of fasteners discussed in this article, including bolts, screws, nuts, washers, and rivets, are versatile and suitable for different applications. When selecting a fastener for a particular application, it is important to consider factors such as the material, size, and grade to ensure a secure and long-lasting joint.
