• Efficient thread-forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and labor costs
• Optimized for plastic applications with TRS thread profile and blunt tip to prevent material cracking and ensure secure fastening
• Quick installation with Phillips No. 2 drive providing reliable torque transfer and reducing tool slippage during assembly
• Flush mounting capability with standard 90° countersink flat head design for smooth, professional finishes in plastic components
• Full threading along 18mm length delivers maximum grip strength and uniform stress distribution across the entire fastened joint
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in industrial and consumer applications

Professional Applications & Engineering Value

These M3.5 TRS thread forming screws are specifically engineered to address common fastening challenges in plastic assembly applications. The 18-8 Stainless Steel composition provides exceptional corrosion resistance, crucial for electronics enclosures, outdoor equipment, and automotive components where environmental exposure is a concern. The thread forming design eliminates the need for separate tapping operations, as the screw creates precisely matched threads in plastic materials without generating chips that could interfere with sensitive components. This makes them ideal for plastic fastening in consumer electronics, appliance manufacturing, and industrial controls where vibration resistance and material integrity are paramount. The combination of 1.57mm thread pitch and fully threaded shank ensures maximum pull-out strength while the Phillips No. 2 drive facilitates efficient high-volume assembly operations.

Specification Summary & Compliance

These metric tapping screws feature M3.5 diameter with 18mm length and fully threaded configuration with standard thread pitch of 1.57mm. The TRS thread forming profile is specifically designed for plastic materials with a blunt tip to prevent material splitting. Manufactured to precise dimensional standards with 90° countersink angle flat head profile and Phillips No. 2 drive compatibility. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications across multiple sectors.
