Rolled Threads

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.

8Feature / Benefit• Heat curled insulator adds ease of pull, protection from

friction, eliminates snagging of wire within fitting
