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 top of the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments. Zinc-plated steel screws resist corrosion in wet environments. Ultra-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.
