S-92470A362 Length 9.5 mm DIN 7981 Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in demanding environments.
• Efficient thread forming technology creates strong, secure threads in sheet metal without pre-drilling, reducing assembly time and labor.
• Optimized for sheet metal up to 0.025" thickness, with a pointed tip and coarse threading for quick, deep penetration and superior holding power.
• Secure and reliable fastening via the Phillips No. 2 drive, providing ample torque transfer and reducing cam-out risks during installation.
• Full threading along the 9.5mm length maximizes grip and distributes load evenly, enhancing joint strength in thin materials.
• DIN 7981 compliance guarantees consistent dimensional accuracy and performance, meeting international quality standards for industrial use.
• Pan head design with 7.5mm diameter offers a low-profile, rounded finish that sits flush, minimizing snagging and improving safety.

Professional Applications & Engineering Value

Engineered for sheet metal applications, these M3.9 metric tapping screws address common industrial challenges like material fatigue and assembly speed. The 18-8 stainless steel provides excellent resistance to rust and oxidation, crucial for outdoor or humid settings. With thread forming technology and a coarse thread pattern, the screw displaces material to form precise internal threads, eliminating the need for taps and reducing hole preparation costs. The pointed tip and fully threaded shank ensure rapid starts and consistent engagement, ideal for high-volume production lines in automotive, HVAC, and electronics enclosures. This design minimizes stripping and vibration loosening, delivering reliable performance in thin-gauge metals up to 0.025" thick.
