S-94209A360 M3 x 20 mm DIN 7500 C Tapping Screws

Key Features & Benefits at a Glance

• Superior material resistance with zinc-plated steel construction providing excellent corrosion protection for long-term reliability in demanding environments.
• Efficient thread-forming design with tri-lobe shank creates permanent, vibration-resistant threads in ductile materials without pre-drilling.
• Optimized for soft metals including aluminum, brass, and copper, delivering secure fastening with reduced risk of material stripping.
• Enhanced drive engagement with Phillips No. 1 drive ensures reliable torque transmission and reduces cam-out during installation.
• Full threading along 20mm length provides maximum grip and holding power across the entire fastener engagement area.
• Precision dimensional control with tight length tolerance (±0.65mm) ensures consistent performance and interchangeability.
• Industry-standard compliance meeting DIN 7500 C specifications guarantees mechanical performance and thread-forming reliability.

Professional Applications & Engineering Value

These M3 thread forming screws deliver exceptional engineering value in applications where vibration resistance and permanent fastening are critical. The tri-lobe shank design displaces material during installation, creating strong, load-bearing threads in aluminum, brass, and copper components without chip formation. This eliminates the need for threaded inserts or additional tapping operations, significantly reducing assembly time and costs. The zinc-plated steel construction provides reliable corrosion protection, while the Phillips drive and pan head configuration offer practical installation in confined spaces. Ideal for electrical enclosures, automotive components, and machinery assemblies, these screws maintain integrity under dynamic loads and thermal cycling.

Specification Summary & Compliance
