S-90469A108 Length 16 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc plating for reliable performance in demanding industrial environments.
• Superior material penetration using a specialized No. 2 drill tip that efficiently cuts through steel and sheet metal up to 0.095" thick.
• Secure, vibration-resistant fastening with a thread-forming design that creates strong, permanent threads without pre-tapping.
• Easy installation and high torque capability provided by the external hex drive and flanged head, which also distributes load evenly.
• Full-length threading ensures maximum grip and holding power across the entire 16mm length for stable assemblies.
• Reliable compliance with DIN 7504 K standards, guaranteeing dimensional accuracy and consistent performance in thread-forming applications.
• Broad industrial applicability in steel and sheet metal fabrication, supported by RoHS 3 and REACH environmental compliance.

Professional Applications & Engineering Value

Engineered for steel and sheet metal applications, these M3.9 zinc-plated steel tapping screws solve common industrial challenges such as material fatigue and assembly time. The thread-forming design eliminates the need for pre-drilled threads, reducing labor and tooling costs while creating durable, strip-resistant connections. The flanged hex head with external drive allows for high-torque installation, ensuring a tight, reliable fit that withstands vibrations. Combined with the fully threaded shank and precision drilling tip, these screws deliver consistent performance in automotive, machinery, and construction sectors, enhancing productivity and fastener longevity.
