Mild-Steel Flange Bolt

If you work with industrial machinery, chances are you’ve come across mild-steel flange bolts. These bolts are commonly used in the oil and gas industry as well as other fields. But what exactly is a mild-steel flange bolt? In this blog post, we will break down the basics of mild-steel flange bolts and what they are used for.

What is Mild-Steel Flange Bolt?

A mild-steel flange bolt is a type of fastener that consists of a cylindrical body with an integrally formed head at one end to form a complete unit. The head of the bolt has two surfaces – an inner bearing surface and an outer bearing surface. The outer bearing surface is tapered for easy insertion into the mating part, while the inner bearing surface helps to distribute stress evenly throughout the joint. Mild steel flanges also feature serrations around their circumference for improved grip on the mating parts.

Mild-Steel Flange Bolt Uses

Mild steel flanges are mainly used in applications where high strength or temperature resistance is needed. They are typically used in industries such as oil and gas, automotive manufacturing, construction, power generation, medical equipment production, and aerospace engineering. This type of fastener can also be found in various types of machinery, such as pumps, compressors, valves, fans, motors, turbines, engines and more.

Mild-Steel Flange Bolt Working

When working with mild steel flanges, it’s important to use tools that have been specifically designed for this type of fastener. It’s best to opt for tools made from hardened steel instead of softer metals like aluminium or titanium because these materials can be easily damaged when dealing with high-torque applications. Additionally, it’s important to ensure that all sides of the nut/bolt are properly lubricated before installation – this will help prevent corrosion and ensure smoother assembly/disassembly operations over time. Finally, it’s essential to follow any instructions from manufacturers regarding proper installation methods to avoid potential damage or injury due to improper handling or misuse of these components.


In conclusion, mild steel flanges are an integral component in many industries and machines around the world today due to their ability to provide reliable and secure connections between two parts under high torque applications. They are relatively easy to install as long as proper procedures are followed during installation/disassembly operations and special tools designed specifically for them are utilized whenever possible. Understanding how these fasteners work can help industrial professionals get better results while working on various projects involving these components!
