Fasteners are essential components of a wide range of machines and equipment, and their significance in industrial settings cannot be overemphasized. Available in various sizes, shapes, and materials, fasteners play a vital role in holding two or more objects together. From buildings, automobiles, aircraft, toys, to medical equipment, the use of fasteners is ubiquitous.
This article will provide you with a comprehensive guide on different types of fasteners, their applications, and materials.
Types of Fasteners
There are numerous types of fasteners, and each is designed for specific applications. However, the following are the most commonly used fasteners in industries;
1. Nuts and Bolts
Nuts and bolts are the most fundamental and commonly used fasteners. They are designed to hold two or more objects together using threads. Bolts are threaded rods that come in various lengths and sizes, while nuts are small metallic pieces with a threaded hole designed to screw on the bolt.
Nuts and bolts are common in automotive, construction, and engineering industries.
Screws are similar to nuts and bolts, but they have tapered bodies with pointed tips, which allows them to be screwed into softer materials like wood and plastic. Screws are also available in various sizes and lengths, and their proper use depends on the material being fastened.
Screws are used in woodworking, cabinetry, and furniture manufacturing.
Washers are thin, disk-shaped metal pieces with holes in the center. They are used in conjunction with nuts and bolts to distribute the load and prevent damage to the objects being fastened.
Washers also come in different sizes and materials, such as steel, copper, and nylon. They are common in the plumbing and electrical industries.
Rivets are cylindrical metal pieces that are inserted through pre-drilled holes and secured on the opposite end using a hammer or specialized tool. They are commonly used in aerospace and automotive industries because of their high tensile strength.
Clips are small metallic pieces with spring-like properties that allow them to attach objects together without the use of screws or bolts. They are common in the electronic and automotive industries, where there is a need for quick, easy-to-remove connections.
Materials Used in Fasteners
Fasteners are manufactured using various materials, and choosing the right material depends on the application and environment. The following are the most common materials used in fasteners;
Steel is the most commonly used material for fasteners because of its strength and durability. It is available in different grades, and each grade has a unique set of properties that make it suitable for specific applications.
Brass is a corrosion-resistant material commonly used in plumbing and electrical industries. It is also popular in jewelry making because of its bronze-like appearance.
Aluminum is a lightweight material that is commonly used in the aerospace and automotive industries. It is also used in construction because of its corrosion-resistant properties.
Nylon is a synthetic material that is commonly used in the manufacturing of washers and clips. It is also prevalent in the electrical industry because of its insulating properties.
5. Stainless Steel
Stainless steel is a corrosion-resistant material commonly used in the marine and food industries. Its resistance to rust makes it ideal for areas with high humidity or water exposure.
Fasteners are undoubtedly essential components of many industrial processes. Knowing the different types of fasteners, their applications, and materials will help you choose the right fastener for your project. Whether you are a manufacturer or a consumer, it's always essential to choose the right fastener and material for the job at hand..
