Midwest Fasteners Steel Zinc Plated Phillips Wafer Head Self-Drilling Screws

Midwest Fasteners Steel Zinc Plated Phillips Wafer Head Self-Drilling Screws

Midwest Fasteners Steel Zinc Plated Phillips Wafer Head Self-Drilling Screws give installers a one-step fastener that drills and taps its own hole into sheet metal and light-gauge steel without a separate pilot hole. This family is available in #8-18 x 1/2" and #8-18 x 1" lengths, letting shops and jobsites match fastener length to panel thickness and application. Every screw in the lineup is manufactured from Steel and finished with Zinc Plating for corrosion resistance and a clean Silver appearance, and the line is made in the United States for consistent quality and sizing. The low, wide wafer head profile sits flush in thin-gauge material for a secure hold, while the Phillips drive allows fast, repeatable installation with standard bits across both available lengths.
