Reusable Lock Nuts

Klincher Tough Locknuts - Proudly used by Nearly Every Major Aircraft Engine Manufacturer.

The Klincher Locknut was designed to be reusable, which is very important for many applications and industries. Many lock nuts, self-locking nuts, high torque lock nuts, prevailing torque nuts / lock nuts and various other similar fastening devices can only be used once! But the Klincher Locknut was designed for re-use as long as it stays within the specified torque values, the threads are not damaged and the overall length stays within the dimension. When these criteria are met, the Klincher Locknut can be reused and retains its locking qualities. Tests have shown that the Klincher Locknut was reusable after as many as 30 times. This reusable quality is one of the reasons why 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.
