Anyone use other than cap/phillips screws in builds?

Well I found MicroFasteners a few years ago, and ever since have really wanted to use the hex heads on something but not being metric I didn't want to have to worry about threading issues.
I'll be using them for building my Volvo'ish truck. My screw box is pretty scarce so I needed to replenish anyway to hold it together once I get going.
I'll use the M3 for main assembly, then get a better idea of needs and order some smaller sizes from MicroFasteners. I'd like to have all the fasteners "nuts and bolts".

You might want to try www.fastener-express.com for metric and SAE nuts and bolts. They have a very large range of sizes and types of materials used. Prices are not too bad either.

Thor. I've used a company in Florida for small hex bolts for my steam engine. They are American Model Enginer Supply. Quite a slection of sizes, both steel and brass. Rob

I use brass M3 hex heads, though I bought overseas. Really low head height of only 1.7mm. Some of the 3mm stuff I have seen still has a bulky head height. I also have 2mm acorn nuts for my wheels because I don't like the socket cap screws. I still use stock screws for stuff that doesn't show.
