I purchased the Scotty backing plate as well. The supplied bolts went into the nylon nuts and all four of them stuck. Three broke loose and snapped the bolt. The fourth one stripped and I had to use a hacksaw to cut it off. Luckily, there was enough room for the hacksaw to cut the bolt. Needless to say, I scratched my boat and had a wonderful time with all of this frustration. I like the whole system, but they supplied nylon nuts are worthless. I had to go to Lowe's and buy replacement bolts and nuts for another $4. The plastic got all scratched up on the rod holder as well as the backing plate. Not very happy with this whole installation process.
