Types of Engineering Bolts

Engineering bolts are used to secure two or more parts together and are typically made from steel. However, they can also be made from metal alloys such as brass and bronze or polymers like nylon or PEEK (PolyEther Ether Ketone).
There are a number of different types of Engineering bolts that design engineers can use in their projects. These include hex head bolts, machine screws and square bolts.

Hex Head Bolts: This type of bolt is a common choice for many projects as they are versatile and can be used in numerous applications. They are threaded on both ends and come in a variety of sizes and shapes.
Square Bolts: These bolts are usually found in railway applications and can be seen as a traditional look. They are often made from stainless steel as they are resistant to corrosion and rust.
They can be used in a wide range of applications and are ideal for industrial environments. They can also be made in a range of finishes to ensure they are protected from rust and corrosion.
Machine Screws: This type of bolt is one of the most popular for a number of reasons. They are strong, easy to fit and come in a wide range of finishes.
The strength of bolts is dependent on their tensile strength and diameter, so they are selected carefully during the manufacturing process. This ensures that they provide the required clamping force to hold together two or more components. This force is calculated during the design stage and will be based on what forces are expected to be applied to the joint.
