Thread Forming (as opposed to thread cutting)

Thread forming and thread cutting are two distinct methods used to create threads in materials, typically for screws or bolts:

Thread Forming

This process displaces material around a pilot hole causing the metal to flow and conform to the shape called ‘plastic deformation’. No material is removed during this process.

Advantages

• Produces a zero-clearance fit, which enhances resistance to loosening.

• Leaves no chips or debris, making it ideal for applications where cleanliness is critical.

• Creates stronger threads due to the cold-working (or work hardening) effect on the material

• Often eliminates the need for additional locking devices, such as lock washers.

  Applications: Commonly used in sheet metal or material where minimizing internal stresses is important.
