Finding supplier of small screws

[Kevin1908]

Two questions to ask here. I am looking for a small countersunk slotted wood screw 3mm shank size. I think a number 6 is just a bit bigger than that. Locally I would go to RS Supplies but the smallest they do is Number 8 or Orbital Fasteners but their web site only has posidrive and Torx and the like.
In the past many years ago I would have gone to Clerkenwell Screws in Clerkenwell Road London. Their phone number answers to a voice mail giving an email address but the emails are bounced.
Whilst I prefer not to do an internet purchase I think I may have to but I prefer direct to a supplier not via Amazon. Any recomendations?

I know you don't want to use online, but you could still call.

I've used KayFast before and they're pretty good, again it's an online purchase though:

Well although the Orbital Fasteners web site only had pozi drive and torx I gave them a ring and they had in stock brass countersunk slotted No 6 3/4 inch long. So managed to buy them just a short drive away. I try to patronise local retailers if I can and on a purchase like that the delivery is likely to exceed the cost of the item.
I will keep a note of the other suggestions for future reference.
