S-92470A378 Length 25 mm DIN 7981 Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 Stainless Steel construction for long-lasting reliability in harsh environments
• Superior thread-forming capability creates strong, permanent threads in sheet metal without pre-drilling
• Maximum holding power in materials up to 0.025" thickness for secure fastening applications
• Easy installation with Phillips No. 2 drive design providing efficient torque transfer and reduced cam-out
• Full threading coverage along the 25mm length ensures consistent grip throughout the entire fastener engagement
• Coarse thread pattern delivers rapid installation and excellent pull-out resistance in sheet metal
• Standard pan head profile with 9.5mm diameter provides a balanced bearing surface for reliable clamping force

Professional Applications & Engineering Value

These M4.8 tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The 18-8 Stainless Steel composition provides inherent corrosion resistance, making these fasteners ideal for applications exposed to moisture, chemicals, or outdoor elements. The thread forming technology eliminates the need for tapped holes, reducing installation time and labor costs while creating stronger thread engagement than cutting alternatives. The coarse threading and fully threaded design ensure rapid penetration and maximum thread contact in thin materials, preventing stripping and maintaining clamp load integrity. These Phillips pan head screws are engineered to solve common industrial challenges including vibration loosening, material galling, and environmental degradation.
