Aerotight® Stiff Nuts

Self-locking all metal nuts, designed to stay in position despite conditions of severe vibration. This is achieved by cantilevered threaded arms which are deflected downwards and inwards.

Two complete threads of the engaged screw must protrude beyond the nut.
Aerotight® nuts should not be used on damaged or interrupted threads.
