Today I was hanging a front poarch light on a friends house. The screws that mount the fixture to the mounting bracket were to long so I cut them off and tried to screw them into the bracket and they would not fit. No problem I got anouther 8/32 it would not fit ether both 8/32??? WRONG.It seems that the mounting screws were 4mm. Now I have been an electrician for 30 years and this is the first time I have seen metric screws on a residential light fixture. Now I have seen european process equipment that'sto be expected but residential lighting??? I guess we are going to have to get metric screw cuters now. Has any one else run across this. THANKS HYPRESS
I run across tham all the time. They are in many of the cheap crap Chinese fixtures sold in the big obnoxious stores. Now I have nothing against the Chinese, or any other race, but the quality of their products is terrible.

Around 1970 the electrical industry switched to metric, adopting 3.5 mm threads on device boxes. Prior to that, device fixing screws were 4BA (BA = British Association).
The diameter and threads look pretty much the same at first glance, but are not interchangeable. As there are still plenty of 1950s/60s boxes in use, it's annoying to find the screws supplied with a modern outlet or switch don't fit the old boxes.
