Set Screw Locking Mechanisms.

This incorporates two AISI 304 set screws spaced 62 degrees apart in the inner ring extension.
The areas around the set screws are high frequency annealed to allow the use of larger diameter set screws further increasing their effectiveness.
The addition of a nylon patch to the set screws prevents their backing out under high vibration situations.
