ARRI screw source?

[Sean Charlesworth]

As some of you know, I service the S and I'm finally starting to run low on certain screws. Over the years I have done searches for sources of replacements with not much luck. It's fairly easy for the standard sizes but ARRI had some oddballs that are hard to find. I've found some stuff at McMaster-Carr, sometimes Micro-Tools, etc.

• Did ARRI make their own screws or source them? Have not been able to determine this.
• What are some good sources for oddball metric screws?
