Too old to remember the pitch on screw holes in ceiling boxes. 8/32? I have to use a tap to clean out drywall mud. Grrrr……

Just use the screws that they supplied. The newer ones have a tapered end on them to avoid cutting the wires. That end pokes into the holes just fine. Then screw it! The drywall will just get pushed out.
I'm thinking some are #8, some #10. All 32tpi, though.
And of course if you have a screw it's easy to check it against the tap to see if they match in thread pitch.
Found a box that took a mud cover and the 8/32" tap went through it. I'm pretty sure they are the same screw.
8 32 on the ceiling boxes and 6 32 on the outlets.
Thanks guys. I could not figure this out on some of the stuff I was installing. But.....found my pitch gauges and mystery solved. The Chinese included nice metric screws! Tossed the metrics and got out the fastener junk box and got real 8/32's and all is wellhttp://www.etherhuffer.typepad.com
Sounds like your problem is solved.
FYI, Klein Electrical Tools has a very cool thread chasing tool, #627-20.
Looks like a screwdriver, 3 taps each on both ends of a reversible bit.
One end of the bit has 6-32, 8-32 and 10-32. Other end has 8-24, 10-24 and 1/4"x20 -- pretty much covers residential electrical applications.
Always rides around in my electrical bag and has saved/shortened the day many times. Got mine at an electrical supply house, but I think I have seen them at various big box stores.

Never underestimate the value of a sharp pencil or good light.
Wow! Nice tool!http://www.etherhuffer.typepad.com

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
Got mine at HDBruceT
