Try an 8- 32 because there are two kinds of countries, ones that use the metric system, and ones that have been to the moon. I just mounted my well-used mount from Quonset on a 1/4" aluminum plate and mine was 8-32 threads.
I've looked long and hard to find which previous post your information was referring to, but this thread goes back many months and I've been unable to find it. I'm assuming you mean try No8 Gauge 32tpi UNC machine screws for the 24 tapped holes in the top of the Kollsman periscopic sextant mount. That's useful to know and will save using a bigger screwdriver. Please state which previous post your comment is in answer to. DaveP
