Thread Rolling

NOTE: We only perform Thread Rolling as a secondary process for parts we are making for customers. We do not perform thread rolling as a standalone service.

What is thread rolling?

Thread rolling is a mechanical process where threads are cold formed when the part is squeezed between two thread dies on a thread rolling machine. Thread rolling provides for a stronger thread and no loss of material.

What are the primary benefits of thread rolling compared to conventional thread cutting?

• Raw material savings
  • 1/4-20 thread pattern produced approximately a 25% savings
  • 3/4-16 thread pattern at approximately 16%
• Increased thread strength over machined threads
  • Tensile strength increase 10%
  • Root hardness increase up to 30%

• Reduced manufacturing times up to 70%

• Superior surface smoothness over other techniques

• Grain Structure retained
