     First of all, don't drill any more holes in your tower.  The damaged 
hole will eventually weaken with rust, especially on the thin steel of an 
HDBX tower.  There are other, non-destructive ways to attach your ground 

     Try McMaster-Carr  for the 
full threaded hardware you need.  I can't imagine that full-thread 9/16 inch 
bolts are unavailable to you.

     If you are truly unsuccessful, you might try an electrical supplier 
that carries Harger connectors.  I used their 213-T  connectors to connect 
the #2 ground wires to my Trylon angle steel tower legs.  Just be mindful 
that they won't tighten too well on smaller gauges than #6 (#8 and above.)
