S-90485A453 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in various environments
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping
• Optimized for plastic applications with TRS thread profile and blunt tip to prevent material cracking and stripping
• Secure fastening performance through No. 2 Phillips drive that prevents cam-out and ensures proper torque transmission
• Flush mounting capability with standard 90° countersink angle and flat head design for clean, professional finishes
• Full thread engagement along the entire 12mm length provides maximum holding power in plastic substrates
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing

Professional Applications & Engineering Value

These M3.5 TRS tapping screws are engineered specifically for plastic fastening applications where traditional threading methods often fail. The 18-8 stainless steel construction provides exceptional corrosion resistance, making these metric tapping screws ideal for electronics enclosures, automotive trim, consumer products, and outdoor equipment where environmental exposure is a concern. The thread forming technology displaces plastic material rather than cutting it, creating stronger threads with reduced stress concentration. This prevents the common failure points of plastic fasteners - cracking and stripping - while the Phillips drive ensures consistent installation torque. The combination of 1.57mm pitch threading and fully threaded design maximizes pull-out strength in various plastic densities, from ABS to polycarbonate.

Specification Summary & Compliance

This M3.5x12mm flat head screw features precision metric threading with standard pitch dimensions and a No. 2 Phillips drive for consistent installation. The TRS thread forming profile is optimized for plastic substrates with recommended No. 34 drill bit (0.111" diameter) preparation. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
