Careful!
Those non-Rohn bolts aren't "shouldered," they're probably "full thread" and,
if so, are specifically not recommended for BX towers apps.
Please investigate.
You could check McMaster or Fastenal.

Keith,
My 1990s Rohn catalog says the leg connecting bolts are SAE Grade 5 steel.
For sections BX-8 through BX-4, 9/16" x 1" bolts are used (48 needed).
For sections BX-3 and BX-2, 3/8" x 3/4" bolts are used (12 needed).
Diagrams show lock washer under each nut.
Such hardware readily available from many sources, such as McMaster Carr or
your local
Tractor
Supply. https://www.mcmaster.com/bolts/hex-head-screws/medium-strength-grade-5-steel-hex-head-screws/
