Powerdrive self-drilling screws (for metal roofing/cladding) consist of three series, each series with a different corrosion resistance class for optimized corrosion protection depending on applied environment.
All series have many fastener lengths with several head-styles and drill-points.
Series available – JR Series, JC3 Series, JC4 Series, and STX Series.

BIMET principlePowerdrive STX® screw series’ head & loadbearing shank is made of non-hardened SUS-304 stainless-steel (18/8) containing 18% Chromium and 8% Nickel, while the drill-point (pilot) section is comprised of hardened steel. This bi-metal principle effectively combines stainless-steel rustfree performance with excellent drilling & threadforming capabilities of the hardened steel pilot section.
