Professional Applications & Engineering Value
Engineered for demanding sheet metal fastening, these M3.5 tapping screws utilize thread forming technology to create strong, permanent threads without generating chips, making them ideal for electronics enclosures, HVAC systems, and automotive panels. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, crucial for outdoor or humid conditions. With a coarse thread and fully threaded shank, they ensure rapid installation and high clamp load, reducing labor time and improving assembly line efficiency. The Phillips drive and pointed tip further streamline the process, minimizing the risk of cross-threading and enhancing overall productivity in industrial settings.
Specification Summary & Compliance
This M3.5 x 25mm tapping screw adheres to DIN 7981 specifications, ensuring precise dimensional accuracy and thread fit. It features a coarse thread with right-hand threading and is fully threaded for consistent performance. The screw is compliant with RoHS 3 (2015/863/EU), confirming it is free from hazardous substances, and meets general industry standards for reliability and safety in sheet metal applications.
