Hillman #12-14 1 in. External Hex Flange Hex-Head Self-Drilling Screw (25-Pack)

Self-drilling screws possess a drill point enabling it to easily drill into material such as thin-gauge steel, wood, and fiberglass. The sharp threads create their own mating thread when drilled into the material. No pre-drilled pilot holes are necessary. These screws are manufactured using #410 stainless steel for best-in-class corrosion resistance in marine applications.
