Sway control threads not bottoming out

I just picked up a new friction sway control for my trailer. The instructions say that the on/off bar or handle should be turned until the threads bottom out. I take this to mean that the threads are screwed all the way in. I have about 1/4 inch of threads showing and I would need a 2 foot pipe to tighten the handle any more. It would definitely bend the handle or break the bolt if I did that. Furthermore, the installation instructions state that I shouldn't need to adjust the adjustment bolt on the bottom of the device more than 1/4 turn or so from the factory setting.
Question: Since the threads won't bottom out the on/off handle supposedly is no longer an on/off handle. Should I screw out the adjustment bolt on the bottom then readjust it after the on/off handles threads are bottomed out?
I have read many postings with people confusing the on/off handle and the adjustment bolt when people have asked similar questions on the web. Can we try not to do that here?
Thanks for any help.

It looks to me like the bolt is bottomed out. "Bottomed out" means the bolt hits the bottom of the threaded hole. It has nothing to do with how much bolt is exposed above the threads. I'm assuming it's a blind hole. If it's just a nut welded to the bar and the bolt is binding before it goes all the way through I'd chase the threads on the nut with a tap.

That said, I have no idea how the connection pictured is supposed to work... Is there some compressible gasket-type material missing between the washer and bar?
