A Comprehensive Guide to Thread Rolling Restrictions

Thread rolling is one of the most commonly used manufacturing processes for producing threads on fasteners. However, thread rolling is restricted to certain materials and thread types. In this blog post, we will discuss the restrictions associated with thread rolling and why it is important to follow them.

What is Thread Rolling?

Thread rolling is a cold-forming process used to produce threads on the surface of a fastener. The process involves the use of cylindrical shaped rolling dies which are pressed into the surface of the fastener. As the dies roll over the surface of the fastener, they form threads in the material. Thread rolling is an efficient and cost-effective way to produce threads and is used in the production of screws, bolts, and other fasteners.

What Materials Can be Thread Rolled?

Thread rolling is restricted to certain materials. It is typically used on materials such as steel, stainless steel, aluminum, brass, and other metals. Thread rolling is not typically used on softer materials such as plastics or composites as they can be damaged by the process.

What Types of Threads Can be Thread Rolled?

Thread rolling is restricted to certain types of threads. The process is typically used to produce bolts and screws with external threads such as Unified (UNC/UNF), Acme, and Buttress threads. Thread rolling can also be used to produce internal threads such as hex and square threads.

Why is it Important to Follow the Restrictions?

It is important to follow the restrictions when thread rolling as it can help to ensure the quality and accuracy of the threads produced. If the wrong materials or thread types are used, it can lead to poor thread quality and inaccurate threads. It can also lead to the thread rolling dies being damaged, resulting in costly repairs or replacement.

Conclusion

Thread rolling is a cost-effective and efficient way to produce threads on fasteners. However, it is important to follow the restrictions associated with thread rolling and ensure that the correct materials and thread types are used. By following these restrictions, it can help to ensure the quality and accuracy of the threads produced.
