HELICOIL® plus thread inserts are made of austenitic chrome-nickel steel (tensile strength of min. 1400 N / mm2) is manufactured. The rolled nut thread has a high surface quality. This ensures a high strength, wear resistant thread with extremely low friction and consistent thread. In repeated bolting a higher and more consistent preload force is achieved this way with the same torque. This results in better utilization of the yield strength of high strength bolts. Torsional stress is significantly reduced: Compared to chopped strands, HELICOIL® surface roughness is furthermore up to 90 percent lower
