• Maximum thread engagement with fully threaded 32mm length design for superior holding power

Professional Applications & Engineering Value

These M3.9 metric tapping screws deliver exceptional value in industrial assembly operations by combining self-drilling capability with thread-forming technology. The specially engineered drill tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs in sheet metal fabrication, electrical enclosures, and HVAC systems. The zinc-plated steel construction provides reliable corrosion protection while maintaining the strength required for steel-to-steel and aluminum assembly applications. With their right-hand thread and 1.4mm pitch configuration, these screws create secure, vibration-resistant connections in materials ranging from stainless steel to insulation panels, making them ideal for diverse manufacturing environments where efficiency and reliability are paramount.

Specification Summary & Compliance

These metric thread forming screws feature precise M3.9 diameter with 1.4mm pitch and 32mm length, manufactured to DIN 7504 N standards with full compliance to ISO 7049 specifications. The zinc-plated surface treatment ensures consistent performance while meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The fully threaded design with 24.5mm minimum thread length guarantees optimal fastening integrity across the specified 2.4mm maximum drilling thickness in compliant industrial applications.
