High Temperature Lock Nuts

The Klincher Locknut is ideal for high temperature / high temp applications. Extreme temperature is a factor that can negatively affect the performance of many lock nuts, self-locking nuts, high torque lock nuts, reusable lock nuts, prevailing torque nuts / lock nuts and various other fastening devices. But the Klincher Locknut was designed for high temperatures / high temp, as well as high vibration, and is one of the reasons jet engine, aircraft and aerospace companies, and other demanding industries, have continued to use them since their introduction in 1943. Dual Machine manufactures both standard Klincher Locknuts, as well as custom Build-to-Print versions for the aviation and aerospace industry, where different dimensions, tolerances and/or threading is required. In these cases, Dual Machine manufactures exactly what you specify for your specific application.
