S-90469A141 Length 38 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for reliable performance in demanding industrial environments.
• Superior material penetration thanks to the integrated drilling tip (No. 3 type), enabling efficient installation in steel and sheet metal without pre-drilling.
• Secure and stable fastening provided by the flanged head design, which distributes load evenly and resists loosening under vibration.
• High-strength thread forming (BSD type) creates durable, wear-resistant threads in the base material for long-lasting assemblies.
• Easy installation and removal with an external hex drive and hex head, allowing for high torque application with standard tools.
• Full-length threading ensures maximum grip and holding power along the entire 38mm length for robust connections.
• Compliance with international standards including DIN 7504 K and ISO 15480, guaranteeing dimensional accuracy and performance reliability.

Professional Applications & Engineering Value

These M5.5 zinc-plated steel flanged tapping screws are engineered to address common challenges in steel and sheet metal fabrication. The thread forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs. The drilling tip (10mm length) efficiently penetrates materials up to 0.207" thick, minimizing the risk of material deformation or cracking. Made from zinc-plated steel, they offer excellent resistance to corrosion, ensuring longevity in harsh industrial settings. The flanged head provides a larger bearing surface, enhancing clamp load and stability, which is critical for vibration-prone applications. Ideal for automotive, machinery, and construction projects, these screws deliver reliable, high-performance fastening while meeting strict DIN 7504 K specifications.
