I'm after supplies of small stainless steel woodscrews. Sizes down to
3mm seem to be fairly easy to find but I can't find anything smaller.

What I'm after is screws in the region of 2mm diameter and lengths
from 10mm to 30mm. I'd prefer pozi head and countersunk but they're
not absolutely necessary.

A2 stainless is fine, these are just for 'ordinary' outdoor use.

Any ideas anyone?

2 x 30 is a big ask but have you tried looking for self tappers and
screws for plastic? essentially the same thing as woodscrews in use but
these small sizes are likely to be more found in other applications.

Well I've looked around in chipboard screws and self-tappers a bit but
haven't really had any joy. Yes 2 x 30 is probably a bit hopeful but
the shorter ones would be very useful anyway.

Must they be stainless?

Zinc plated Model 'servo screws' fit the bill perfectly.

They do have to be stainless really, many will be used on a boat and
my experience is that standard zinc/yellow plates screws don't last
long before rusting and marking the wood. My TurboUltra screws seem
to survive well.

I would go to a chandlers or look on ebay.
