Professional Applications & Engineering Value
These M3.9 tapping screws deliver exceptional engineering value by solving critical assembly challenges in metal fabrication and construction. The zinc-plated steel material provides corrosion protection while the self-drilling tip eliminates the need for separate drilling operations, significantly reducing installation time and costs. The thread forming design creates precise, strong threads in various materials including sheet metal, aluminum, and stainless steel without generating chips that could interfere with electrical components or moving parts. With fully threaded construction and metric thread standards, these screws maintain consistent clamping force across the entire fastener length, preventing loosening under vibration in industrial equipment, HVAC systems, and structural applications.
Specification Summary & Compliance
Manufactured to DIN 7504 N and ISO 7049 standards with metric thread specifications including M3.9 diameter, 13mm length, and 1.4mm pitch. Features right-hand threads with fully threaded design and pan head configuration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications.
