I'm worried those nylon screws will become brittle and fail in a few years time. But, I'm not sure. Does anyone here have experience with these? I can get a hold of these pretty easily.
I like the titanium bolts I see online from Chinese exporters, but I don't want to put my project on hold any more than the time it takes for the rubberized paint to cure (24-48 hours). So, it doesn't have to be from the local hardware store, just no obscure, online only, ten days to ship warehouses.
I like the rubber bushing idea. Maybe something like those blue drywall screws which expand and grip the wall; only it would have to be shorter and without gaps. A prefabricated options would be nice.
It's a simple problem. It likely has a simple answer, I'm sure there's a right way to go about doing this, it's been done a hundred times. I thought I was overlooking something obvious.
