Hi All.
I have been searching for something quite trivial, however, have not been able to find it anywhere; probably because I don't know what it's called!
It is basically a washer which goes behind a mirror, etc. when screwing to a wall to protect the glass, however, it is not just a flat round thing with a hole; it has a raised part which goes INTO the hole of the mirror to protect it from the screw. Hope someone knows what these are called and where I can get them.
Another question I have is, if I do manage to locate these washers, where do I stand with regards to sizing of washer to hole? Also, would a snug fit between washer and screw and also screw and washer be ok, or does mirror/glass have a tendency to expand and be susceptible to cracking?
Thanks.
