Testing the HARDLOCK

The HARDLOCK Nut has successfully met the testing requirements of multiple vibration and impact tests, including the NAS3350 and 3354 National Aerospace Standard.  These tests demonstrate that our products  provide effective locking force and remain in a stable locked condition.

Vibration testing based on the National Aerospace Standard (NAS3350) demonstrate the overwhelming superiority of the locking effect when compared with other products under identical conditions.
