Two comments on regulating screws:

 Firstly, cut down on breakage by using the right tool.  There is 
nothing like those good old rigid regulating screwdrivers to break off 
eye screws.  A proper regulating screw driver has some "wobble" on the 
eye screw, allowing you to turn the screw without being exactly in line 
with it.  Better yet is a tool with a flexible shaft, allowing wonderful 
access from "bad" angles.  See:

If a screw breaks off and can't be turned out, I prefer to drive it 
through with a fine punch instead of trying to dig it out.  This is 
faster, more secure, and leaves a smaller hole to fix.  I use hammer 
shanks to fix this situation, drilling in from the side of the rail so 
that the new screw goes through cross grain, not end grain wood.

If you drill a blind hole from the back side of the rail, this repair is 
essentially invisible
