Below are some common questions we receive. Please contact us with additional questions.
How Does the Klincher Locknut Work / How is it Different?
The Klincher Locknut has a free spinning design to reduce the stress concentration found in the first three threads of a nut and bolt. This allows more wrench torque to be applied to the Klincher Locknut without plastic deformation to the bolt. The nut spins freely on the bolt down to the workpiece. After proper torque has been applied to the Klincher Locknut, the integrated washer compresses, causing the threaded section inside the washer to move in and lock radially and axially on the bolt. When the threads absorb a maximum load, they elongate a few thousandths of an inch, allowing the majority of the load to move up into the main body of the nut.
What Industries and Applications use Klincher Locknuts and/or Klincher Kapscrews?
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. Klincher Locknuts and Klincher Kapscrews are commonly used in the following industries and applications:
Aerospace / Aviation
High Temperature Applications
High Vibration Applications
High Stress Applications
Are Klincher Locknuts Reusable?
Unlike many lock nuts, the Klincher Locknut is reusable 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. Note that these tests were done on the standard Klincher Locknuts, not the custom, modified Build-to-Print versions used in some industries.
What Sizes do the Klincher Locknuts Come In?
Klincher Locknuts are available in the following standard sizes. Custom Build-to-Print versions with modified dimensions, tolerances and/or threading can also be manufactured (such as for the aviation and aerospace industries).
