Professional Applications & Engineering Value
Engineered for industrial efficiency, these M3.9 metric tapping screws with thread forming capability solve common assembly challenges by eliminating tap holes and reducing installation steps. The zinc-plated steel material resists rust, ideal for outdoor equipment, HVAC systems, and automotive panels where exposure to moisture is a concern. With a Phillips drive and pan head, they ensure easy torque application in confined spaces, while the self-drilling tip effortlessly penetrates sheet metal, aluminum, and stainless steel up to 2.4mm. This design minimizes material stress and thread stripping, providing reliable fastening in construction, machinery, and electrical enclosures where vibration resistance and long-term hold are critical.
Specification Summary & Compliance
This screw meets DIN 7504 N and ISO 7049 standards for dimensional accuracy and thread forming performance, with a metric M3.9 size, 1.4mm thread pitch, and right-hand thread. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in industrial and consumer products without hazardous substances.
