The Klincher Locknut is a self-locking nut designed for demanding applications and industries like the jet engine, aircraft, aerospace and aviation industry. Many self-locking nuts attempt to address these more demanding applications, but none perform as well as the Klincher Locknut due to its unique design. Photoelastic studies at a major US university have shown an equitable distribution of stress over the entire Klincher Locknut, versus a severe stress concentration in the first few threads of typical prevailing torque nuts and self-locking nuts. This unique stress pattern created in the Klincher Locknut effectively lowers the strain on the bolt, allowing it to perform better and for a longer period, including repeated uses. Note that these studies were done on the standard Klincher Locknuts, not the custom, modified Build-to-Print versions used in some industries.
High torque, high temperatures, high vibration, high stress, etc. are factors 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 these environments and is one of the reasons why so many 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. We are also ISO 9001:2015 and AS9100:2016 Certified.
When high vibration, tensile strength, corrosion and temperature are factors, companies rely on Klincher Locknuts. The Klincher Locknut’s unique design, even distribution of stress and loads, and ability to be reused, make it the perfect lock nut for demanding applications. Klincher Locknuts are commonly used in the following applications:
