M3.5 Alloy Steel Phillips Flat Head Self-Tapping Screws

These steel screws are zinc plated to resist corrosion in wet environments. All are beveled under the head for use in countersunk holes. Often referred to as Type B thread-forming screws, they require a drilled hole and are typically used in 0.050″-0.200″ material. Length is measured from the top of the head.
