Machine Screw Between a #6 and #8?
Is there a machine screw size between a 6 and an 8? I’ve got a fan that I am putting together and the bottom uses flat stainless machine screws to hold the bottom on. I’ve tried both a #6 and a #8. The #6 slides in without screwing and the #8 is too big and won’t screw in at all. I was thinking maybe they are metric but the other screws for the fan were all standard.
I should also note that one screen that I do have that came with the fan seems to screw into the #8 tester at the store but doesn’t scream into the #6 or into any of the metric options.
Any help would be greatly appreciated.

I actually haven’t. I didn’t think in those sizes they had fine and coarse. I’m not sure what I’ve got. It went into the #8 thread checker at the hardware store, as did the replacements I bought. Although the existing one was a little wobbly in the threads.

Kind of. They don’t seem to match right in the store but I’ve yet to buy. 4mm might be the right size. Might.

They do make odd sizes (literally!) of machine screws, but they are specialty items. Usually available only on special order, the minimum quantity would probably take your breath away.
Sounds like it may be time for a #6 nut-sert or a #8 self-tapping screw.

I believe that for that type of fastener it will be a fine thread. Or you fixture has damaged threads preventing the screw from cleaning threading.
These are usually called a B*ST*RD thread and made as to prevent you from DIY fixing or copying by other manufactures. I doubt a self tapping screw would be used in this case.

I wouldn’t be surprised if the threads were damaged. An M4 seemed to work well enough apparently. So odd that every other screw was SAE and this one worked with a metric and the one screw I did have seemed to not work in a metric but. Oh well at least it’s fixed.
Thanks everyone for your help!
