I have a slidemaster jack plate. Also have power poles. Question I have is there lock nuts on the inside of the plate where the bolts come out of the black plate. The inside plate is threaded but I had lock nuts(cap nuts) on the inside. Problem is the bolt is not long enough for the cap nut to lock on and they come loose. Do Yall have longer bolts, stubby cap nuts or no nuts on the bolt? Does not seem to need lock nuts on the inside, just wondering if there is a reason they are there?
