VIBRATION TESTING

Field Testing

The best way to test the Security Locknut (or any fastening solution) is on the product in the field. This will create actual load, vibration, and environmental conditions that cannot be fully simulated in a laboratory.  We support this monitored testing with our field testing program.  General program information is available by contacting us directly for more information.


Laboratory Testing

Vibration testing using the NASM 1312-7 protocol. This standard that establishes a procedure for conducting accelerated vibration tests on any fastener system capable of providing a clamp-up load. The bolt/nut combination is installed in the fixture, the fixture is subjected to controlled vibration and times/cycles until the assembly loosens. The Security Locknut performed exceptionally well in tests against other commonly used products. 

A summary of the test results are shown below.
