Free Spinning Locknuts

Free-spinning locknuts are designed to turn freely on a bolt until they are firmly seated against a base and further tightened to produce the locking action. This feature can be advantageous in applications where ease of installation and adjustment are required, as the nut can be quickly positioned by hand before other locking or securing methods are applied.

In addition, most free-spinning designs can be loosened and retightened several times before losing their vibration resistance.
