Dave,
I would drill and tap the closest backing plate with a 10-32 or 1/4-20
thread and use a standard lug. I might even consider a 5/16-18 thread
and use a standard premade ground cable.

I need to replace my mast grounding wire with 4 AWG (according to my
surveyor). It appears to connect at one end to the aluminum base
plate of the mast and that nut is accessible and a new cable can be
attached with a lug. I have not yet found the other end. Could it be
under the keel bolt? I have been thinking of ways to attach to a keel
bolt. The easiest would be if I could put a large enough lug on the
end to go over a keel bolt and then put another nut on top. I have
not found a lug that large so this may be moot. Can you buy a keel
bolt nut? Anyone know the spec or a source? Could I trap a large
lug between the existing keel nut and a second one? An earlier thread
discussed using braided copper instead but that appear to contradict
ABYC standards. Any suggestions on the best/easiest way to do this?
Thanks- Dave
