Good point Steve...it hadn't occurred to me to use coarse threads.
I'll be needing to safety-wire the bolts, so I'd ordered (and have in
hand) AN3H-3 bolts...looking again in the Acft Spr cat., I only find
10-24 threads in some cap screws w/ slots for single blade screwdrivers.
Guess I'll settle for what I have...and if the threads strip, upsize
to 1/4 dia. bolts...
