5/16" x 1" Self-Drilling Screws, Hex Washer Head, #3 Point, 18.8 Stainless Steel

Hex Head Self Drilling Screws create their own hole and form their own mating thread in the process. Designed for convenience, hex head self-drilling screws require only a screw gun to fix them in place instead of using a drill to start the hole. When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined.
