Mechanical locking devices (such as split washers, nylon nuts, etc.) were invented to solve the common problem of loosening that happens in most threaded assemblies. The reality is, however, that they don’t maintain clamp load as assemblies “locked” with mechanical devices often loosen under vibration, thermal expansion and/or improper torque. Why? Because mechanical devices don’t fill the gaps between the engaging threads. By bonding the thread roots and filling all of the gap, eliminating side-to-side movement, LOCTITE® threadlockers have dramatically increased the reliability of threaded assemblies by preventing fastener loosening – a leading cause of catastrophic equipment failure.

Try if for yourself.
