I replaced the bridge saddle screws on my L2500 Tribute with socket head cap screws like this:
I got them from a local industrial supplier in stainless steel and they cost me $0.81 total. Now when I adjust my intonation I don't have to worry about stripping the phillips head out at all or pushing hard so that it doesn't slip - it's an easy grip with a hex wrench.
If you're interested I can get you the screw specs.
