Miniature plow-bolts for cutting edges/routers

[dozerbuilder]

I was wondering if anyone has had success in obtaining miniature plow-bolts for cutting edges and end bits/routers for dozer blades. I guess the primary requisite is a flat or domed "recessed" head, the square shank wouldn't matter since its out of sight. At 1/16 they'd be M2 or M2.5 or even M3 would do. I have got some really good M2-M5 scale bolts and nuts from RC4WD's international site that I learned about here but I haven't found anything that resembles a plow-bolt with a recessed head. Miniature carriage bolts may do, again I haven't found any in M2-M3 size. Any ideas guys?

Thanks in advance.

Cheers
