S-90469A109 Length 19 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments.
• Efficient installation through the external hex drive and hex head design, allowing for high torque application and secure fastening.
• Self-drilling capability with a specialized drilling tip that eliminates pre-drilling, saving time and labor costs in steel and sheet metal applications.
• Enhanced holding power from the flanged design, which distributes load evenly and prevents pull-through in thin materials.
• Consistent thread engagement with fully threaded, right-hand thread forming (BSD type) for reliable, vibration-resistant connections.
• Wide material compatibility, optimized for use in steel and sheet metal up to 0.095" thickness, providing versatile application solutions.
• Regulatory peace of mind with compliance to DIN 7504 K, RoHS 3, and REACH, ensuring safety and environmental standards are met.

Professional Applications & Engineering Value

This M3.9 x 19mm zinc-plated steel tapping screw is engineered to address common challenges in industrial assembly, such as the need for speed and durability in steel and sheet metal applications. The thread forming (BSD) design creates strong, permanent threads without chip removal, reducing the risk of loosening under vibration. Combined with the flanged hex head and external drive, it ensures easy installation with standard tools, while the drilling tip penetrates up to 0.095" thick materials, eliminating separate drilling steps. Ideal for automotive, HVAC, and machinery sectors, this screw enhances productivity by minimizing assembly time and providing reliable, long-lasting fastening solutions that withstand demanding conditions.
