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

Yep, all those high end LV hand blown glass too expensive for my house jobs. My favorite is metric mounting plates, holes are set wider than 3/0, and smaller than 4/0.

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.

If you can use a regular screw (it's not a fancy brass thing) just run the 8-32 part of your triple tap through the hole. Then it will be 8-32.

You do carry a triple tap don't you?

We have a similar problem here in England.

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.

Reminds me of "Chinese Standard Thread"

Usually 8.25 / 32 or thereabouts...

I bought some of these to supplement my Klein triple tap.

I call those chinese 8/32. There just metric. What I hate is when you have those chinese 8/32 trim nuts. You can't tap it out cause it's not deep enough.

Maybe the rest of the world hate those american screws. They say why are they so fat?

Those are nice Doug. Solves the problem of having to have a tap drill and a tap. Everybody should have at least a 10-32 for those times you need to install a ground screw.

Gotta get them myself!
