To provide rotational support at the connections[*], I have been
planning for machine screws in pairs. Space is tight, so that has

one 8-32 screw and making a tight-fitting slot to prevent rotation at
each connection. Any preference or other ideas?


Press-fit a dowel in one piece and slip fit it in the other, then you can
use one larger screw.

larger screw and a roll pin?
