Oval Head Drilling Screws for Metal
A decorative rounded top provides a finished appearance. These screws are beveled under the head for use in countersunk holes. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from the edge of the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments. Zinc-plated steel screws resist corrosion in wet environments. Corrosion-resistant-coated steel screws are more corrosion resistant than zinc-plated screws.
18-8 stainless steel screws have good chemical resistance and may be mildly magnetic.
410 stainless steel screws are stronger and more wear resistant than 18-8 stainless steel screws. They have mild chemical resistance and are mildly magnetic. Not for use with aluminum.

Drilling Screws for Joining Fabric to Metal
These screws have a free-rotating, permanently attached washer that remains stationary while tightening to prevent bunching while attaching tarps and other fabric to metal. They save you time and effort by drilling their own holes and fastening in a single operation. Made from steel, they're zinc-plated to resist corrosion in wet environments. Length is measured from the edge of the head.
