saddle height question

I set up my guitar with 0.010" relief at the 8th fret (when fretted at the 1st and last fret simulatneously), and about 3/32" action at the 17th fret at the low E. The action gradually gets closer to 5/64" at the high E.

Pretty normal so far? I don't know if it is, but it's what works for me. I tune down half a step if this matters...

My problem is that at these settings, my saddles are pretty high. The 3/8" set screws used for height adjustment are screwed all the way into the saddles and almost all the way out the other end. Everything works and sounds fine (great actually), but it looks as if one of the saddles could collapse under the strings tension because the screws are barely hanging in there. I kinda doubt this would happen, but I'd like longer screws for more stability.

The longest I've seen are 3/8". Anybody know where to get longer ones (between 3/8" and 1/2")? The ones are need are 4-40 by the way. Thanks.

One thing you could do is to put a small shim in the neck cavity behind the uppermost neck bolts. This will raise the action and let you lower your saddles.

Other options would be to have about 1/32" shaved from the neck pocket, but that may be a bit too drastic. The easiest option would be FUZZY's nickel trick: a nickel under each pair of saddle screws....

I actually thought of shaving the neck pocket down as I was typing my previous post, but it just seems like such a drastic move. Plus the fingerboard begin to sit in the neck pocket and some of the side marker dots will partially obstructed. It's just not cosmetically nice.

I never thought to put something under the saddles (like nickels!). I think I'll look into this option. Will the nickels fall out when re-stringing? I guess I'll find out...

The nickels probably wouldn't fall out, but if they did it would be easy enough to slide them back in.

Personally, I'd shim the rear of the neck. A very thin slice of hardwood would probably do the trick and be practically invisible.
