H.S.S. thread dies are very rare. They are designed to thread micro precision threads on rod stock. These die threads are used by knife and gun makers to create a maximum adjust threading, or to create a thread that is less prone to "back-out", a common issue with standard coarse threads. Try a die thread on your next project and you'll never go back, or back-out again!!!
