**What are flange bolts?

Flange bolts are a type of fastener that are used to securely attach two components together with the help of a flange attached to the bolt head. They are commonly used in construction and manufacturing industries for their ability to provide a durable, strong, and leak-proof joint. In this article, we will dive deeper into what flange bolts are, their types, how they work, and their applications.

**Types of flange bolts:

Flange bolts come in various types depending on their design and application. The most common types of flange bolts include:

1. Serrated Flange Bolts: These bolts are designed with a serrated flange that helps to distribute the pressure evenly, preventing the bolt from loosening over time.

2. Non-Serrated Flange Bolts: These bolts have a flat flange that does not have any serrations. They are commonly used in applications where the external surface of the flange needs to be flush with the surface of the component.

3. Hex Flange Bolts: These bolts have a hexagonal flange attached to the bolt head. They are commonly used in automotive applications due to their ability to withstand high levels of torque.

**How do flange bolts work?

A flange bolt consists of two parts: the threaded shaft and the flanged head. The threaded shaft is screwed into a threaded hole in one component, while the flange on the head of the bolt is placed on the surface of the second component. When the nut is tightened onto the threaded shaft, the flange gets pressed against the surface of the second component, forming a rigid joint. The flange provides a larger surface area, which helps to distribute the load and reduce stress on the joint. The serrated flange helps to grip the surface and prevent the bolt from rotating.

**Applications of flange bolts:

Flange bolts are used in a variety of applications where a strong and secure joint is required. Some of their most common applications include:

1. Construction: Flange bolts are commonly used in construction for attaching beams, columns, and other structural components.

2. Manufacturing: Flange bolts are used in manufacturing for attaching machinery components and other parts together.

3. Automotive: Flange bolts are frequently used in the automotive industry for attaching important components such as engines and transmissions.

4. Plumbing: Flange bolts are used in plumbing for attaching pipes, valves, and other components together.

5. Aerospace: Flange bolts are used in the aerospace industry for attaching structural components and other parts together.

**Conclusion:

In conclusion, flange bolts are a type of fastener that is commonly used in construction, manufacturing, automotive, plumbing, and aerospace industries. They are available in different types, each designed for specific applications. Flange bolts provide a sturdy, durable, and leak-proof joint, making them ideal for applications where reliability and safety are critical. It is important to choose the right type of flange bolt for the specific application to ensure maximum performance and durability.
