What is proper way to fix knob in precision mirror mount?

07 May 2021 1 9K Report

I have precision mirror mount, which control mirror angle by 2 positioning screws.

These screws slowly loosened during usage, so I have to rotate regularly to maintain exact mirror angle.

I first thought to apply loctite, but did not cause worrying that it might permanently fix screws immovable and become unable to adjust anymore.

Can you suggest any good method, to add little more friction to screw?

thanks,

Jae Hwan Jeong

1. Remove excess lubricant. Too much lubricant may cause the issue. Wipe it cleanly.

2. Apply weak screw adhesive. ex) loctite threadlocker 222.

Some weak screw adhesive model give enough friction to screw to not loosen, while keep screw removable and rotatable by bare finger.
