Aerospace Manufacturing at Superior Thread Rolling

For over 70 years, Superior Thread Rolling has been the thread rolling and aerospace manufacturing supplier of choice.

We specialize in manufacturing and engineering critical and flight safety components with demanding applications in Aerospace, Defense, and other industries requiring challenging high-strength steels and exotic materials.

AS9100 Certification for Aerospace Manufacturing

Because our company serves the aerospace industry, we understand the unique requirements for quality management that are listed under AS9100 certification. With the challenges of the aerospace industry in mind, AS9100 sets a guideline for manufacturers of aircraft components and materials, designers of aerospace parts and assemblies, quality management organizations working with aerospace manufacturers, and other companies that regularly work in the aerospace industry. This certification accounts for factors such as Counterfeit Parts Prevention and risk management, amongst many other common aerospace concerns.

What Is Thread Rolling and How Does It Pertain to Aerospace Manufacturing?

We provide excellence in manufacturing high-strength, fatigue rated parts in the aerospace & defense industry since 1952.

The thread rolling process greatly increases a part’s fatigue life. Superior Thread Rolling continues to research and invest in the latest threading technology, including CNC thread rolling and inspection equipment, to guarantee we produce the highest performance threads available.

Superior Thread Rolling specializes in rolling threads after heat treatment. We routinely produce threads on parts made of the hardest materials (up to 54 HRc) with a size range of #0 up to 6” diameter.
