The OP is doing exactly as Freesail99 implied and a perfect example of this.
Sabre 28's have through bolted stanchions many times installed with round top machine screw heads.
The OP thinks he's unscrewing screws while in reality he's only broken any remaining water tight seal he had left by twisting the "bolts", with screw heads, or machine screws as they are referred to as. Most times the nut on the under side just spins because some bedding compound got onto the threads and is acting like Loc-Tite..
