Professional Applications & Engineering Value
These M3.9 Phillips pan head tapping screws deliver exceptional engineering value in sheet metal assembly applications where corrosion resistance and thread integrity are critical. The 18-8 stainless steel construction provides superior protection against rust and chemical exposure, making these thread forming screws ideal for outdoor equipment, electrical enclosures, and HVAC systems. The coarse thread pattern combined with full threading ensures maximum engagement in thin materials, preventing stripping and maintaining clamp force under vibration. The pointed tip facilitates quick alignment and starts threads accurately, reducing installation time and improving production efficiency in high-volume manufacturing environments.
Specification Summary & Compliance
This metric tapping screw features precise dimensional specifications including 7.5mm head diameter, 2.8mm head height, and 13mm length with fully threaded coarse pitch right-hand threads. Manufactured to DIN 7981 standards for dimensional accuracy and performance consistency. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use in electronic and consumer product applications. The thread forming design meets Type C specifications for creating strong, reliable threads in ductile materials without pre-drilling requirements.
