S-92470A373 Length 38 mm DIN 7981 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-drilling, reducing installation time
• Optimized for sheet metal applications with pointed tip and coarse threading for maximum grip in materials up to 0.025" thickness
• Secure Phillips drive system (No. 2 size) provides reliable torque transfer and prevents cam-out during installation
• Fully threaded shank delivers maximum holding power across the entire fastener length for superior load distribution
• Standard pan head profile offers excellent bearing surface while maintaining a low-profile appearance
• DIN 7981 compliance guarantees precise dimensional accuracy and consistent performance in industrial applications

Professional Applications & Engineering Value

This M4.2 tapping screw delivers exceptional engineering value in sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making it ideal for outdoor equipment, electrical enclosures, and HVAC systems. The thread forming technology eliminates the need for separate tapping operations, reducing labor costs and potential alignment issues. The coarse threading and pointed tip design ensure quick starting and secure fastening in thin gauge materials, while the Phillips drive enables efficient installation with standard tools. These metric tapping screws are engineered to prevent stripping and maintain joint integrity under vibration and thermal cycling conditions common in industrial environments.
