I tried the screws from the Android. They are a hair too thick. I wasn't worried about the length I knew they would be longer and wider compared to the CD. The ends are slightly thicker and would not screw in without damaging the threads in the CD tubes.
These are the measurements from the CD tubes and parts.
thread diameter 0.88mm
screw head thickness 1.42mm
screw head length including threads 4.24mm
tube diameter 1.30mm
tube length with head attached on one side 21.54mm
tube length with both heads attached 23.00mm
These were what I would consider using, but you need to find thinner/smaller diameters. The thickness on these are for larger holes. The reason I say these would be a good option is one head end is friction and the tubes can be cut down in length.

These band tube, pins, screw and friction head band pins are can be used on many different watches, including extra large watch cases.
Can be used in a variety of ways: The standard, strongest way which is to have the pin inside the tube and the friction head and threaded head on each side. Another option is to just use the tube and heads. Finally, the heads can be used as replacements for lost heads.
The tube is smooth on one end to be easily cut to fit many different lengths and this is the end that the friction head fits onto and the other is threaded to hold the threaded head. The solid pin fits inside the tube for added strength and no crimping.
- Made of Stainless steel
- Pin set is sold individually, in a set of 4 pieces: tube, pin, friction head and threaded head
- Made to be easily cut to the length you need - Note: Cut the friction fit end NOT the threaded end.
- The tube is friction fit on one end and threaded on the other end
- To order the size you need: Use the tube diameter and head diameter
- To use just the heads: Use the head and thread diameter
