Thomas & Betts
Rolled Threads
Forming threads offers many advantages over cutting threads. One of these
advantages is the fact that rolled threads are cleaner since the forming tap displaces
metal and no metal chips or fragments are produced. Cutting taps produce metal
chips that may interfere with the tapping process, cause poor tap lubrication and tap
binding or breakage.
Rolled threads are generally stronger than cut threads due to cold working of the
metal in conjunction with the fact that the grain flow of formed threads follows the
contour of the thread. Further, primarily because metal is not cut away, rolled thread
production greatly decreases the possibilities of producing oversized threads.
