S-90227A115 Length 16 mm ISO 15482, DIN 7504 P Tapping Screws

Key Features & Benefits at a Glance

• Enhanced Drilling Efficiency: Self-drilling tip with 5.9mm length eliminates pre-drilling, saving time and labor in steel and sheet metal assembly.
• Superior Corrosion Resistance: Zinc-plated steel construction provides reliable protection against rust, extending service life in industrial environments.
• Secure Fastening in Tough Materials: Thread-cutting design creates precise mating threads in steel and sheet metal up to 0.089" thickness, ensuring strong, vibration-resistant connections.
• Optimized Drive Engagement: Phillips No. 2 drive offers efficient torque transfer and reduces cam-out risk during installation.
• Flush, Professional Finish: Standard flat head with 80° countersink angle sits seamlessly in materials for a smooth surface and improved aesthetics.
• Full-Length Thread Engagement: Fully threaded shank maximizes grip and distribution of clamping force across the entire length for enhanced joint integrity.
• Global Compliance Assurance: Meets ISO 15482 DIN 7504 P specifications and environmental standards (RoHS 3, REACH) for safe, reliable use in regulated industries.

Professional Applications & Engineering Value

These M3.5 x 16mm zinc-plated steel tapping screws are engineered to address common challenges in fastening steel and sheet metal components. The thread-cutting design and integrated drill tip eliminate the need for separate drilling and tapping operations, significantly reducing assembly time and potential alignment errors. The fully threaded right-hand thread ensures consistent engagement, while the zinc plating offers durable corrosion protection in demanding environments like automotive framing, electrical enclosures, and HVAC ductwork. By combining ISO 15482 DIN 7504 P compliance with a Phillips drive and flat head profile, these screws deliver reliable performance, minimize installation tooling requirements, and support efficient high-volume production lines.

Specification Summary & Compliance

This M3.5 x 16mm tapping screw features a fully threaded round shank with standard thread tolerances per ISO 15482 DIN 7504 P specifications. The zinc-plated steel material and thread-cutting tapping method ensure consistent performance in steel and sheet metal applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms adherence to environmental safety standards for industrial use.
