Description
The ARRMA ARA708009 Flanged Lock Nut set contains four M3 flanged lock nuts, used throughout ARRMA vehicles including the Kraton 6S platform.
A lock nut differs from a standard nut in that it resists backing off under vibration. RC vehicles vibrate constantly from the motor, the drivetrain, and every impact the suspension absorbs, and a plain nut will gradually work its way loose in that environment. Lock nuts hold their position, which is why they are specified anywhere a fastener coming undone would cause a real failure.
The integrated flange spreads clamping load across a wider area beneath the nut. That protects composite and aluminum parts from being crushed or dented as the nut is torqued down, and it removes the need for a separate washer, which is one fewer small component to drop or lose during a rebuild.
Lock nuts are consumable by design. The locking mechanism relies on interference with the thread, and that interference wears down each time the nut is removed and refitted. After several cycles a lock nut spins on freely and no longer does its job, which is why they should be replaced periodically rather than reused indefinitely.
These are direct factory replacements that install in the stock locations with no modification. Four nuts are included.
