Fasteners may not be the most glamorous topic, but when it comes to construction or manufacturing, they play a critical role in holding things together. A fastener is a hardware device that mechanically joins two or more objects together. It can be anything from a simple screw to a complex stud bolt or a rivet. In this article, we will explore the basics of fasteners, their types, uses, and some interesting facts related to them.
What Are Fasteners?
Fasteners are mechanical devices that are used to join different materials together. They come in various shapes, sizes and materials, depending on the application. Some of the most common forms of fasteners are bolts, screws, nuts, washers, pins, and rivets. Fasteners are usually made of metal or plastic and are designed to hold objects together under tension or compression.
Types of Fasteners
Fasteners come in a variety of types and sizes. Choosing the right one for a specific application is important to ensure that the joined objects remain secure. Here are some commonly used types of fasteners:
Screws - Screws are one of the most common types of fasteners. They usually have a threaded shank and a tapered point, which allows them to be inserted into a material without the need for a pre-drilled hole.
Bolts - Bolts are similar to screws, but they are usually larger and made of stronger materials. They are also threaded, but they require a pre-drilled hole for insertion.
Nuts - Nuts are used in conjunction with bolts, and they serve to secure the bolt in place. Nuts can be either hexagonal or square shaped.
Washers - Washers are small flat pieces of metal that are used to distribute the load of a fastener over a wider area. They can be either plain or spring-loaded.
Rivets - Rivets are used to permanently join two objects together. They require a pre-drilled hole and a special tool to install.
Uses of Fasteners
Fasteners are used in a wide range of applications, from construction and automotive to electronics and aerospace. They are essential components of almost every product that is manufactured. Fasteners are used to join two or more objects together, and their purpose is to hold those objects in place under tension or compression. Here are some common uses of fasteners:
Construction - Fasteners are used to join different parts of a building or a structure together, such as roof trusses, I-beams, concrete forms, and more.
Automotive - Fasteners are used extensively in the automotive industry for assembling engines, transmissions, suspensions, and other parts.
Electronics - Fasteners are used to secure printed circuit boards, connectors, and other electronic components.
Aerospace - Fasteners are used in the construction of aircraft, spacecraft, and missiles. They need to be strong, lightweight, and durable.
Here are some interesting facts about fasteners:
The oldest known fastener is a bronze nail that is over 5000 years old.
The world's largest fastener is the Millenium Bolt, which is over 20 feet long and weighs more than 12,000 pounds.
The first machine to make screws was invented by Christopher Columbus's grandson.
The modern screw thread design was invented by a Frenchman named Philippe Metdepenningen in the 18th century.
In conclusion, fasteners are essential components of almost every product that is manufactured today. They come in various shapes, sizes and materials, and their purpose is to join two or more objects together. Fasteners play a crucial role in construction, automotive, electronics, and aerospace industries. Understanding the basics of fasteners can help you choose the right type for the job, and ensure that the joined objects remain secure..
