Intonation Screws issue - Seems to be a PRS issue.

[Andy Power]

I have two PRS Guitars a Modern Eagle V 2020 Expo ltd and a PRS Special.
The intonation screws have come out of my ME-V and have had to be replaced on 3 occasions, last night the top E string Intonation screw came out on my PRS Special rendering it unplayable as the saddle flips up....
In all my years as a professional musician this has never happened in any guitar I have owned except on my two PRS guitars - and these are the most expensive....
obviously theres an issue.

Most common cure is a dab of clear nail polish to keep them in place.

 

[Andy Power]

Good call, but I have never had to do this with any guitar in the passed, it must be a PRS issue - same bridge on both instruments...

High E? Probably doesn't have a whole lot of intonation spring pressure...
Longer/stronger spring or like 'sparky' says,"nail polish".

It has happened twice on the D and once on the G on my Modern Eagle V also.

Odd, I’ve never heard of this before, though I have had a trem screw back out on its own a few times on one guitar. PRS issue or not, you’d best take it on yourself to put it on your maintenance checklist before a gig. You could always shoot an email over to PRS support and see if they’ve had complaints on it or have a more permanent fix option for you.

Are they from around the same time? If so, most likely a bad batch. Maybe PRS can replace your bridge for free.

If it's happening on these 2 guitars and not just one or not from another brand, then it's definitely a PRS fault, not yours, not wherever you bought it.

Weird...
Are those particular saddles adjusted to their limit(minimal spring pressure)?

Never heard of this in the 33 years I've been playing PRS! I've been on the forums since 2000, too.

I've had a lot of PRS guitars since then - 35-40 over the years - and it has ever happened.

It isn't a normal PRS thing. Perhaps your setups are far enough from factory spec that they're very unusual.

I’ve got five core PRS is with tremolos, one of them 26 years old and have never touched them after adjustments. Never had one change, loosen or move after adjustment.

 

[Prs Mods too]

It happens. I've heard this complaint maybe twice in the last 20 years.

Unfortunately you'll have to fix it somehow. Locktite or nail polish is the easiest bandaid, next would be a stronger spring. Otherwise you'll need to replace the saddles and screws.

I've had it happen on one PRS, and only with one saddle. But it has happened.

I think I'd use a tiny dab of silicone before I'd use clear nail polish.

The silicone will peel off more easily than nail polish.

I used silicone on hex nuts on 1/4 inch female speaker jacks that kept coming loose. Worked very well.

 

[Simon Says]

Never had that sort of issue either, but I always played 11s so I give no chance to saddles to wiggle

 

[Whackmaster]

Not common, but not unheard of. It happened to me once, on a 2008 Custom. For context, I've had over a dozen over 30 years.

 

[Greywolf]

Never had the problem , but as others have said , check the setup , and a lil dab will do ya .. locktite blue

 

[Prs Mods too]

and a lil dab will do ya .. locktite blue

Pshhh! If you're going to invest the time do it right.

Break out the welder!

Blue loctite will keep it from moving.
