#10 x 1-1/2 in. Wafer Head Phillips Drive Self-Drilling Screw 1 lb. Box (109-Pack)
Everbilt. $18.99. In stock.
This self-drilling screw is used in wood, fiberglass, and metal, and it possesses a drill point enabling it to drill its own hole in thin gauge steel. No pre-drilling is necessary. The sharp threads create their own mating thread when drilled into the material. The wafer head is designed to offer a clean, smooth finish that sits flush with material when fully installed.
