I used wax in the socket (melted candle) and loaded the nylok nut. I taped the socket wrench to the batten, attached the socket w/nut, aligned the nut to the screw and tightened with a screwdriver (with help from my wife). I did this in several places on the back beam of the A2 because the rivets for attaching the tramp were breaking (since corrected by the factory).
