S-90380A366 Length 16 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping
• Maximum torque transfer through No. 2 Phillips drive prevents cam-out and ensures secure fastening
• Material-friendly blunt tip prevents cracking or damage to plastic components during installation
• Full threading along 16mm length provides consistent holding power across the entire engagement area
• Precision 1.57mm pitch ensures reliable thread engagement and vibration resistance in plastic assemblies
• Standard pan head profile offers low-profile fastening with excellent bearing surface distribution

Professional Applications & Engineering Value

These M3.5 thread forming screws are specifically engineered for plastic applications where traditional fastening methods often cause material stress or failure. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength needed for durable assemblies. The TRS (Thread Rolling Screw) design displaces plastic material rather than cutting it, creating stronger threads that resist stripping and loosening under vibration. With fully threaded configuration and blunt tip design, these screws eliminate the risk of plastic cracking during installation while ensuring maximum thread engagement. The No. 2 Phillips drive delivers reliable torque transmission for consistent installation in automated or manual assembly processes, making them ideal for electronics enclosures, automotive trim, consumer products, and industrial equipment where plastic components require secure, long-lasting fastening solutions.
