The Importance of Bolts and Various Bolt Types By Bolt-on
Bolts are part of the threaded fasteners family and are always paired up with threaded nuts normally to join two or parts together. Bolts are categorized into various types corresponding to their discrete head shapes, strengths, finishes and materials. These classifications play a part in the selection of a bolt sort for a certain job. It is vital to develop the needed knowledge to pick the right bolt type for the job because there is loads of different designs of bolts that are better suited for a specific job than others.
Types of Bolts and Their Uses
Bolts like screws come in various types of head shapes. These heads are manufactured to grasp the tools being used to tighten them. Some examples of the most common are; hex, socket cap, square and slotted hex washer.
The first bolt heads used were the square heads. The square head as the name would suggest have a square groove on the head supported by a shaft that endures rotation when a force is applied to it. Whilst square heads are still in use today hex heads have now become more common. Hex heads are utilized with a spanner or a wrench to provide a force.
There are many other types of head shapes such as round head, button head, oval head, pan head and flat heads.
Here are some other Bolt Types and what they are used for.
Bolts have markings on them which to categorize their strength, which is dependent on the material used to make the bolt and also the dimensions used to make it.
The finish of a bolt is the coating used on a bolt material. Finish can vary from minimal to high quality.
The selection of a suitable fastener material for a specific application is very important. This is due to the fact that bolts are used for both light weight applications and for heavy duty applications hence why it is important to be chosen correctly.
A bolt made of steel rather than aluminium can make a big difference to the quality and toughness of the joint it forms. Other factors such as the environment, presence of corrosive as well as structural strength can affect the materials efficiency.
Some of the bolt materials include:
Steel is the most commonly used material as it is easily molded, its flexible and durable. Its not too expensive to manufacture and it is widely available. It is available in many different alloys to provide different degrees of strength to suit different applications.
Stainless steel is an alloy that mixes the characteristics of low carbon steel with particular amounts of nickel and chromium. The chromium makes it resistant to corrosion whilst the low carbon protects from hardening.
Bronze and Brass
Bronze is an alloy made up of copper and tin which provides high resistance to corrosion. For this reason, it is ideal for use in underwater constructions such as ships and submarines etc. Brass is made up of zinc and copper which also provides high resistance to corrosion and develops a soft material.
A lightweight, artificial material made up of plastic. Nylon is resistant to corrosion is better insulated both thermally and electrically, and it can also be easily died. However, nylon is prone to melting if it is exposed to high temperature and can weaken in lower heat.
Everyday worldwide bolts are keeping both tall structures and small components in position. There are many ways to arrange the bolt types and their uses. All the factors above will make up the final decision of the bolt to be used in a certain project.
