These screws have a deep thread for more holding power. Looks like a high quality galvanized product. Its countersunk heads allow the screws to stick firmly to the surface. It has a deep recess on the screw head that is perfect for a screwdriver. It comes with a small plastic box, which is nice, but the plastic lid of the box doesn't feel solid and is difficult to open. In fact, I broke it the first time I tried to open the lid. Overall, the screws are of good quality and I like them.
