Does anybody know what the bolt size is that GE uses in their service
panels for attaching hardware to the box? The thread pitch looks like a
32 tpi when I lay a thread gauge or tap next to it. The major diameter
is about 0.185" and the root diameter is about 0.168". This puts it in
between a #8 and a #10.

Thanks,

Are those multiple thread bolts?

It looks like a single start thread to me. Also, it has a slightly
tapered area near the end. Not a notch like a full self tapping screw,
but suggesting that.

probably 10/32

Think its a 10-32 with a paint/thread chasing taper on the end. Use
one of the screws ( or a tap tool) to clean/chase the hole and a 10-32
seems to fit well.

Most electrical hardware is standard machine screw size, it's probably
10-32 with a self-tapping, tapered tip. A few boxes of 10-32, 8-32
and 3/16"/10-24 screws should handle just about any electrical
hardware problem.

You forgot 6-32. Used in electrical boxes.

It was 10/32. I put a 10/32 tap in one of the holes in the box and it
was a tight fit, but I put a 10/32 nut on the bolt and it was acceptable.

4-40 is popular for small stuff; I've even seen 3-48 and 2-56. One place
where I worked, they were calling out 0-80's but this was for an electron
gun or something. ;-)
