Saddle screws not staying in place

[JQ1986]

I bought an Ibanez SR-305 last week and after a week of tinkering with the set-up I got it where I want it, but the saddle screws (mainly the ones for the B-string) keep coming un-screwed. I'll get it where I want it then after 20 min of playing I hit the B-string and it's laying flat on the fret board. How do I get them to stay in place?

A drop of clear nail polish can serve to stop the setscrew from shifting.

But that much shift in 20 minutes sounds very exceptional. Are any of the other strings doing this also?

+1 I've been doing this to my basses for years&years.No damage whatsoever to the finish on the bridge and body.I do it to ALL of my basses whether it needs done or not.Nothing worse than extreme fret buzz. Better to be safe than sorry.

It'll do it slightly on the A and G strings, but the B is the worst. I'll try the clear nail polish idea. Do I just put a drop right on top of the screw? I've never tried something like that before so I'm kinda clueless.

Tiny drop where the screw threads meet the saddle. Small drop using a toothpick should work well. Don't need much, unless there are other problems.

Clear works fine. Black works fine. I'd avoid pink; embarrassing when the guitarist is borrowing something out of your toolkit.

I'm thinking there is either some issue or you are a really strong picker. You can also try swapping saddles (like trade the E & B) to see if a saddle's screwholes are slightly worn.

APPLICATION TIPS:Back out the saddle screw to where there is just 1 or 2 threads in the saddle.Apply f/nail polish to ALL of the threads,adjust accordingly,give it ample time to cure.Jam away.Will not harm finish in any way.Oh,one more tip.Hot pink works best.

Well I know I have black fingernail polish around here somewhere from when I went as Twiggy for Halloween one year so I'll try that when I find it. Thanks
