S-90227A121 Length 16 mm ISO 15482, DIN 7504 P Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drill tip technology, reducing installation time and labor costs in steel and sheet metal applications.
• Superior corrosion resistance provided by the zinc-plated steel construction, ensuring long-term durability in demanding industrial environments.
• High-strength, secure fastening achieved through the thread-cutting BSD design, which creates clean, precise mating threads for a reliable hold.
• Streamlined, flush installation enabled by the standard flat head with an 80° countersink angle, ideal for applications requiring a smooth surface finish.
• Optimized for high-volume assembly with a No. 2 Phillips drive, offering a common and efficient drive interface for power tools.
• Full-length threading ensures maximum grip and holding power along the entire 16mm shank length for superior joint integrity.
• Guaranteed material and process quality through compliance with ISO 15482 and DIN 7504 P manufacturing standards.

Professional Applications & Engineering Value

These M3.9 tapping screws are engineered to solve common fastening challenges in steel and sheet metal fabrication. The zinc-plated steel material provides a robust base for corrosion resistance, while the thread-cutting (BSD) design and integrated drill tip eliminate the need for a separate drilling and tapping operation. This self-drilling capability significantly reduces assembly time and potential errors in high-volume production lines, such as in HVAC ductwork, electrical enclosures, and metal frame construction. The fully threaded shank and Phillips flat head ensure a secure, flush fit, making these screws a reliable and efficient solution for industrial professionals seeking to optimize their fastening processes.
