#12-14 x 4" Self-Drilling Screws with Galvanized Bonded Washers, Hex Washer Head, #3 Point, TanCor Corrosion Resistant Coating - Made in the USA (Melted & Poured)

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.
