Rich,
The manual calls for Grade 5, 3/8-24 steel.
Mine has this size in stainless steel with lock nuts.
The bolts are 4" long.
The bolts that attach the clamp to the mounting plate are 3/8-24 x 1 1/2".
The mounting plate on my rotator has threaded holes and through holes.
I use through stainless steel bolts and lock nuts.
