Apart from the obvious, I need 2mm dia' brass countersunk nuts and bolts, but only about two dozen of them
In this area anything less than will hold a timber bridge together is considered sissy and is unavailable - I can get 2mm ones to special order, but I will need to buy a kilogramme of them
Try some of the online modelling shops. How long do they need to be, I'll drop into a couple of local screw shops while out tomorrow and see what they have.
When I needed to get screwed, I got my M2 hardware from Microfasteners in Lebanon NJ. 1-800-892-6917. They had a website but it isn't listed on the label. I seem to recal the price was reasonable and they offered small quantities. My experience at hobby shops (even the ones specializing in radio control) wasn't as good -- they seemed to have low stock in small screws, or pre-packed screw sets for specific vehicles that were VERY expensive.
