S-96817A326 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in various environments
• Enhanced torque transmission through T10 Torx drive design, reducing cam-out and tool slippage during installation
• Efficient thread forming action creates strong, permanent threads in plastic materials without pre-tapping requirements
• Integrated flange design provides wider bearing surface for secure fastening and prevents over-tightening
• Full threading along 12mm length ensures maximum grip and holding power throughout the engagement area
• Optimized 1.57mm thread pitch delivers excellent pull-out resistance in plastic substrates
• Blunt tip design allows for precise positioning and reduces material stress during installation

Professional Applications & Engineering Value

These M3.5 metric tapping screws are specifically engineered for plastic fastening applications where reliability and installation efficiency are critical. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for durable assemblies. The thread forming design (TRS type) creates precise mating threads in plastic materials through material displacement rather than cutting, resulting in stronger connections with reduced stress concentration. The combination of T10 Torx drive and fully threaded flanged design ensures high torque transmission during installation while the wide pan head distributes clamping force evenly, preventing damage to delicate plastic surfaces. These features make them ideal for electronics enclosures, automotive trim components, and consumer products where secure plastic fastening is essential for product integrity.

Specification Summary & Compliance

These metric M3.5 x 12mm tapping screws feature standard ISO thread tolerances with 1.57mm thread pitch and fully threaded construction. The screws conform to TRS (Thread Rolling Screw) specifications for thread forming applications in plastics. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial standards for hazardous substance restrictions and chemical safety requirements.
