What the Hex Lock Nut does
A lock nut differs from a plain nut in that it resists backing off once torqued — through a nylon insert or a distorted thread that grips the bolt. On a hard-working commercial vacuum, vibration steadily loosens ordinary fasteners, so lock nuts are used where a joint must stay tight, such as motor, axle, or handle mounting points. This nut keeps its joint secure between services.
Signs the Hex Lock Nut needs replacing
Replace the hex lock nut whenever it has been removed (the locking feature wears with each use and should not be reused indefinitely), or if the joint it holds has worked loose, the nut is corroded, or its locking feature no longer grips so it spins on freely. A fastener you can turn by hand along the full thread has lost its lock and should be renewed.
Installation and fit
Thread the new 30358 lock nut onto its bolt and torque it to seat the joint; you should feel the locking feature engage before the nut is fully seated. Do not reuse an old lock nut on a safety-relevant joint. Twin City Vacuum has sold and serviced CleanMax equipment since 1956, and every part is sourced directly from Tacony.
