In my case it seems the ‘normal’ stuff isn’t an issue, it’s the non-normal stuff that I have to identify. -8 TPI series, -20 TPI series, and large acme threads (like 4-8” diameter acme) are all examples of stuff I’ve came across in the last couple years.

And do not forget the buttress threads.

It always fun finding metrics and Imperial threads on the same cylinder. Sometimes it it even seems to come from the factory that way. Other times, we might have seen the cylinder before for a repair, and if we needed to make a rod and piston, the other machinists would change the metric threads to imperial because it would be easier for us to machine. Don’t have keep the half nut engaged and reverse lathe to reset for next pass on our lathes.

Dump every nut and bolt you can find into a couple of 5 gallon buckets then sit down and sort them. Either you will get good at seeing the difference or you will have at least a bucket and a half of hardware that needs sorted. At work there is 2 of us in a separate building and there's a lot of misc hardware around. We have been sorting by diameter during lunch breaks for the last couple of months. We are getting to have a nice selection and are starting to think we should keep it out of sight so we don't have everybody digging in our work.
Last winter I cleaned and sorted our bucket of plastic capplugs now I and the other guy have nice assortments of plastic plugs, the rest of them went back in the bucket.

If I were going to make a set, although it would be more work, I would make the set out of steel rather than Aluminum.

Hi,
I have the sort that Digr posted.

I have both Metric and Imperial sets.They are good for most applications bar threading on fixed studs where they are difficult to thread over the stud because of the other sizes on the wire.

To make them might a big PITA unless you have the time and patience.

Mine are steel ,stamped for size and pitch and zinc plated. Purchased here in Australia of course.
