Bimetal Pan Head Self-Drilling Screws
Product Details
Fasto Bi-metal pan head self-drilling screws are precision-engineered for high-speed installation in corrosive environments. By fusing a high-grade stainless steel body with a super-hardened drill point, these fasteners provide a one-step solution for drilling, tapping, and fastening into metal structures without the need for pre-drilling.
Advanced Dual-Material Fusion : Combining the permanent rust protection of SUS 304/316 with a hardened AISI 420 drill point. This allows the screw to penetrate thick steel plates while maintaining long-term structural integrity in harsh coastal or chemical climates.
Low-Profile Pan Head Design : The rounded, slightly domed head provides a clean, professional finish and a broad bearing surface. This design is ideal for securing brackets, thin-gauge sheets, or components where a flush yet secure attachment is required.
Precision Drive System : Available in Phillips or Torx drives. The high-precision drive geometry ensures maximum torque transfer and minimizes cam-out, reducing tool wear and ensuring consistent installation depth.
High-Speed Self-Drilling Point : Equipped with a specialized No.3/No.5 drill tip, these screws are capable of simultaneous drilling and tapping through heavy-duty metal sections, significantly reducing labor time and onsite costs.
Specialized Protective Coating : Finished with a Ruspert or Water-based Wax treatment to enhance lubricity during drilling and provide an additional barrier against atmospheric corrosion and chemical exposure.

Applications
Our Bi-Metal pan head self-drilling screws are engineered for maximum efficiency in metal-to-metal fastening applications. Combining high-speed drilling performance with permanent atmospheric corrosion resistance, they provide a clean, professional finish for structural and decorative mounting in demanding environments.
Light-Gauge Steel Framing : Ideal for securing steel studs, tracks, and metal bracing in residential and commercial framing where a low-profile head is required for surface clearance.
Solar & Photovoltaic Systems : Perfect for mounting aluminum rail components, solar panel brackets, and junction boxes on rooftops, especially in coastal or industrial areas with high salt spray.
Marine & Offshore Installations : The SUS 304/316 body ensures long-term integrity for boat fittings, seaside boardwalk railings, and offshore equipment housing without the risk of rust bleeding.
HVAC & Ductwork Assembly : Designed for rapid assembly of galvanized steel ventilation ducts, air handling units, and exterior AC unit casings, providing vibration-resistant fastening.
Electrical & Enclosure Mounting : Optimized for fixing outdoor electrical cabinets, control panels, and cable trays to metal structures, ensuring a secure and weather-proof attachment.
