Spectralock® technology modifies basic joint behavior instead of relying on thread friction. Its asymmetric thread design limits the clearance between threads to create three specific contact points engaging with the female thread form. The Spectralock® patented design is an advantageous fastening solution which allows for a standard female threaded hole to utilize this self-locking bolt for consistent locking and reusability in situations where cyclic or high temperatures are present and severe vibration occurs.
