RE: thread lock on servo screws?
Like most of you that responded to this thread.....I have never had a servo arm keeper screw get even loose......but.....if you're worried about it.....I wouldn't over-kill it with thread lock....instead....a little dob of varnish or fingernail polish on the screw wouldn't hurt....and besides.....when you need to remove the screw, a little acetone will release it. Down pressure with your phillips screwdriver is NOT good.
