If the thread is turned too much in one direction, it can become over-tightened and difficult to ring the bell.

It is important to find the right balance when adjusting the thread to ensure the bell functions properly. **

The skateboard axle cannot be tightened because it is designed to pivot and rotate freely to allow for smooth turning and maneuverability.

It is common for braces to cause some discomfort or soreness after they are tightened.

The discomfort typically lasts for a few days and can be managed with over-the-counter pain medication and soft foods. It is important to follow any post-tightening care instructions provided by your orthodontist to help alleviate any discomfort. **
