Dan- The only problem with that is the bolthead would try to unscrew if turned counterclockwise. Schempp-Hirth provided a rigging tool with the Arcus that has an allen head bolt inset in the face of the tool and we ran into that issue.

If you only turn it clockwise, it isn't a problem. I might incorporate that idea if people request it.

Sorry, I should have been more clear, I didn't mean to use a threaded bolt per say. I agree it would have to be a "solid" installation that could be turned either way and not unscrew.
It would be a nice option. It's a great tool.
Good luck,
Dan
