Attention to detail with fasteners is a big deal for us. Every fastener we use is specific to the application. It would be grossly impractical for us to pre-order anything. We try to standardize on 10-32 thread size, button head for most things and countersunk flat head for bearing blocks, but there are plenty of areas where 10-32 thread is not a good choice. We spec our fasteners, and order from McMaster when needed, and they show up a day or two later.

We do keep a lot on-hand, but it's all remnants from the above, and used primarily for prototyping and maintenance purposes.
