I stock 1" long #8 black wood screws, so let me know if you need 'em and I'll mail you out some.For sealing purposes, there are a number of different gasket materials you can use. If the joint is two flat surfaces, a cardboard gasket works well and it is easy to install and remove. Silicon and caulking materials form a good seal, but they often stain wood and are harder to clean and remove.
