Small screw #8 x 3/4 Phillips Flat Sheet Metal Screws. Pretty straight forward. Phillips head. Goes great with the P-hooks and Stayput hardware.
It isn't that we are cheap, it is just that many of our customers use their own screws and don't want/need ours, so we need to make it an option for those who don't have screws. Anyways, they are cheaper and more convenient than running down to the local big box.
10 count minimum.
