Key Features & Benefits at a Glance
- Eliminates pre-drilling with a self-drilling tip that penetrates up to 2.25mm thickness in steel, stainless steel, and aluminum, saving time and labor.
- Superior corrosion resistance from the zinc-plated steel construction, ensuring long-term durability in harsh industrial environments.
- Excellent driving torque and strip-resistance provided by the No. 2 Phillips drive, allowing for secure and efficient installation.
- Maximum material engagement and holding power due to the fully threaded design with a 1.3mm pitch and minimum 15.1mm thread length.
- Reliable thread forming action creates strong, permanent threads in ductile materials without generating chips.
- Wide application versatility for use in steel, stainless steel, aluminum, fabric, insulation, sheet metal, and wood.
- Secure and stable fastening from the rounded pan head design, which provides a good bearing surface and a low-profile finish.
Professional Applications & Engineering Value
These M3.5 metric tapping screws are precision-engineered to solve critical assembly challenges in metalworking and construction. The thread forming design eliminates the need for a pre-tapped hole and prevents chip formation, making them ideal for sealing applications in sheet metal, aluminum frames, and stainless steel enclosures. The hardened self-drilling tip effortlessly pierces materials up to 2.25mm thick, drastically reducing installation time and tooling costs. Manufactured from zinc-plated steel, they offer reliable performance in HVAC, electrical enclosures, and general fabrication, providing a robust, vibration-resistant connection that maintains integrity under stress.
Specification Summary & Compliance
This screw conforms to the dimensional and performance requirements of DIN 7504 N (ISO 7049) for thread forming tapping screws. It features a standard Metric M3.5 thread with an approximate pitch of 1.3 mm and is fully threaded. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
