ABSTRACT:
A fastener which includes a threaded pin having a notched helical thread to receive a threaded collar which, after being set to a torque, is deformed to move material into some notches on the thread to form a lock to prevent unthreading. The notched thread can be formed by a three-section roll die, the first section of which forms the thread, the second of which notches the thread, and the third section of which smoothes the thread. The invention comprehends the die, the die forming method, the pin, the pin and collar, and a joint formed with the pin and collar.
