suppliers of small self tapping screws (#0 and #00)

[spoolman]

does anyone know of a supplier of small self tapping screws that will ship to Canada or are in Canada. Apparently McMaster-Carr does not ship to Canada.

Micromark may have them but don't know if they ship to Canada:

Alternatively precut the thread and use non-tapping screws instead. Worked for me and should be the most easy solution for many DIY application, as non-tapping screws are more eaysy to obtain.

I have had good experiences with these 2 suppliers.

Taps aren’t a bad idea. I have 1-72, 0-80 and 00-90 with the corresponding drills and a variety of screws and nuts that come in handy from time to time.

Sometimes you can just twist the taps between fingers

I was not referring to readymade taps, as typically these would be even harder be to obtain, if at all. (So far I only once came across self-tapping screws at an appliance that were of classic, metrical thread.)

How 'small' were you thinking about?

See title: sizes #0 and #00 (whatever this is..., maybe a reference to a Philips head)

One of the above linked sites has a chart of the numbering system.
The number designation seems to relate to the major diameter of the the screw thread:

Thank you! We have not got such system in Europe.

In the US, really good toy stores carry screws in the model / RC car / train section. My favorite toy store closed down so not sure where to go next.

Here is a decent chart showing these small sizes.

https://pages.mtu.edu/~suits/misc/tapsizes.htm

Three common small (US) sizes, for example, you would be a #53 drill for a 1-72 tap. #55 drill for a 0-82 tap and a #61 drill for 00-90.

For reference, you probably know a common larger size, #7 drill for a 1/4-20 ( tripod mount ).

This chart is helpful but doesn’t show the smaller sizes.

If you can find a business selling model trains and cars, they might be able to help.

I have no idea either.

Would this work ?

Well, my reply was due to one of these terminology misunderstandings again...

In Germany we understand by self-tapping a screw that actually cuts its own thread, in similar way as a thread tap does. Actually these exist in metrical threads, though for some reason I had now versions with non-standard threads in mind. And as said I turned a non-tapping, non-standard-thread screw into a tap for other samples.

Basically each classic (old) wood screw is self-tapping in the meaning of this thread, but they got an unfavourable shaft/thread ratio, so that often they need pre-drilling, so that screws with straight shafts and other ratios were designed.
