Use a drop of “replaceable” (blue), LOCTITE thread locking seal ? It will hold the screws in place nicely, but can still allow removal or just loosening, if needed. That would be my first choice, but confirm with AP.

I am having some issue with the springs holding the worms in DEC. I screw the bolts fully in and then I unscrew them by 1.5 turns. However after a couple of nights observing I check the bolts only to find that they unscrew themselves during the imaging session. What is the best way to set the tension on the worms and keep it there.
Thank you for your help.
