Threads are either cut or rolled.
Cut Threads are produced by removing material (cutting) from the outer surface of the wire that is the nominal diameter of the desired thread, leaving behind the thread shape.
Rolled Threads are formed by pressing a thread pattern into the wire causing material to flow down to create the root of the thread and up to form the crest of the thread. The wire diameter is the thread's pitch diameter. No material is removed in this process.Advantages of Wire Forms with Rolled Threads
The rolled thread is more cost efficient in a number of ways.
