10 Thomas & Betts 8Feature / Benefit Steel Body with Tapered Threads Added Durability & Strength Consistent Threads, Easy to Install Double Plated for Superior Corrosion Protection Rolled Threads

11 Thomas & Betts 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. Rolled Threads

12 8Feature / Benefit Thomas & Betts Heat curled insulator adds ease of pull, protection from friction, eliminates snagging of wire within fitting Heat Curled Insulator
