Can anyone advise what type and size screws are used for the covers?

A couple of mine seem stripped and cross threaded.

I want to replace them.

Thanks

rnolan:
A common problem it seems.  I have stripped threads in many of my units (well no doubt we all do) and I'm overly meticulous when I take them out and always put the same screw back in the same hole.... :facepalm: .  The ADA screws are imperial (as are US), if you go metric (but very slightly larger) it may fix it.  MJMP posted the screw sizes ages ago and there is a post or 2 about this (do a search of the posts).  Or maybe he'll post here again.

Those screws are 4-40 x 1/4 philips head ,countersunk. If the holes are stripped you can use M3 screws since these are only slightly larger then the 4-40, but best to use a M3 tap to put some new thread in there. Works great, done this with a few of my units. Just be carefull that no metal bits fall into the PCB.
