Has anyone noticed light fixtures being supplied with non-standard size screws? By non-standard I mean screws that don't fit right, don't tighten etc (possibly metric?). I have noticed this myself and was just trying to determine how widespread it is. This may be limited to certain inexpensive residential-type fixtures, and not those sold in Supply Houses. If anyone knows anything on this subject or has noticed this I'd appreciate hearing about it.
