Zinc-nickel alloy Phillips screws Built-in cushion screw Round head with self tapping screw

Product Features

• ‌Corrosion & Wear Resistance‌: Zinc-nickel alloy coating offers superior protection compared to standard zinc plating, ideal for humid or salt-spray environments‌.

• ‌Self-Tapping Design‌: Sharp tip allows direct fastening into metal sheets, plastics, or wood without pre-drilling‌

‌Integrated Washer‌: Built-in washer distributes pressure evenly, prevents surface damage, and reduces assembly steps‌.

• ‌Cross-Recess Compatibility‌: Pan head with Phillips cross-recess (ISO 7049) ensures secure engagement with standard screwdrivers or power tools‌.

• ‌High Stability‌: Combined pan head and washer design enhances contact area, suitable for high-vibration applications‌.
