I am replacing the pedestals on my boat with shock mitigation posts.
When I removed the stock pedestal base, the screws appeared to be machine screws, fine thread. They are a nice snug fit and I just cant imagine they are getting that good a bite on the wood.
Anyway, I am thinking there might be some sort of threaded sleeve down in those holes that provide the expansion and bite. I can't see any but the holes are a good 2" deep.
Anyone know for sure?
Since the holes on the new pedestal do not quite line up with the old holes, I have to treat and fill the old holes and drill new ones. Should I use the same machine type screws or use a standard SS wood screw.
PS. There is absolutely no adhesive or caulk under the existing pedestal.
