Gearhead, a few months i went searching for wooden inserts, real small ones(M3) for a certain project iwanted to try.
I went to almost every engineer shop local, and no one had, until i got lucky with one shop, there where 2 shops, BESCO and NESCO(the one specialises in nuts and the other in bolts).
But its in cape town, so probably a dead end.
what about fastener agencies, there are probably closer to you, although they have not replied to any of my emails ever:

I can i ask them if they have something like that if i go there again.
