Hillman 1/4 In. - #14 x 1-1/2 In. Washer Head Self-Drilling Sheet Metal Screw (100-Count)

Self-drilling screws are manufactured for use in wood, fiberglass and metal.

They possess a drill point which enables the screw to drill its own hole in thin gauge steel; no pre-drilled holes are necessary.

The sharp threads create their own mating thread when drilled into the material, and provide a stronger grip to your surface.

Perfect for roofing construction, these screws have a neoprene washer that provides a water-tight seal, and prevents corrosion between surfaces.

Zinc. 100-piece per package.
