Thread rolling is a cold forging process that can be performed on any ductile metal. The forming process can be used to produce other special forms, such as knurls. For the best quality threads, the process is performed on precision centerless ground blanks.

The blank diameter of a rolled thread is at the pitch diameter, a theoretical point between the major diameter and minor diameter.

Thread rolling is the preferred method for producing strong, smooth, precise, and uniform external thread forms. Thread rolling is different from other types of threading processes like cutting, grinding, and chasing.

What is mean by thread rolling?

In SS 410 thread rolling is used but it is ductile.

Since ductility states the metal can be deformed. Particularly at thin thread structures it will definitely deform.
