"Robertson Screws" for metal frames?

[kev@frames]

Supplied some mats for aluminium frames which were made for a customer who lived in Canada. The frames need to be taken apart to change the mounts, and they are unfortunately held together with square head screws, called (the custome believes) Robertson screws. Where would I find him a Robertson yellow head number 0 for a 3/32” socket?
any ideas?

Screwfix do them, but they seem to start at #1 size.
