How to correctly use sheet metal screws?
Sheet metal screws use a self-drilling tip to create a hole in a material. The threads of the screw cut into the material to hold the screw in place. The self-drilling tip of a sheet metal screw dulls rapidly when it contacts the glass fibers contained in fiberglass. This leads to cracks forming in both the fiberglass and the gel coat covering ...
