S-94209A354 M3 x 5 mm DIN 7500 C Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming capability for reliable, permanent fastening in ductile materials like aluminum, brass, and copper without the need for a pre-tapped hole.
• Exceptional vibration resistance due to the Tri-Lobe shank design, which prevents loosening under dynamic loads and ensures long-term joint integrity.
• Enhanced corrosion protection from the zinc-plated steel construction, extending the screw's service life in various industrial environments.
• Optimized torque transmission and reduced cam-out with the Phillips No. 1 drive, allowing for efficient installation and minimizing driver slippage.
• Wide material compatibility specifically engineered for non-ferrous metals, providing versatile application across different projects.
• Guaranteed dimensional precision with controlled length tolerance, ensuring consistent performance and ease of assembly in high-volume production.
• Full regulatory compliance with major industry and environmental standards, offering peace of mind for global supply chain integration.

Professional Applications & Engineering Value

This M3 x 0.5mm thread forming screw is engineered to solve common fastening challenges in aluminum, brass, and copper assemblies. Its Tri-Lobe shank and thread forming design displace material to create strong, wear-resistant threads, eliminating the risk of stripping in soft metals and reducing assembly time by removing the tapping step. The zinc-plated steel material provides a durable, corrosion-resistant finish, ideal for electronics enclosures, automotive components, and HVAC systems where reliability is critical. The Phillips drive ensures straightforward installation with standard tools, making it a cost-effective choice for high-volume manufacturing while maintaining vibration resistance and joint security.

Specification Summary & Compliance

This screw adheres to DIN 7500 C standards for thread forming screws, ensuring precise thread geometry and performance. The M3 coarse thread (0.5mm pitch) and 5mm length with a specified tolerance support consistent fit. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications.
