S-99461A978 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 humid or demanding environments.
• Excellent thread-forming capability in plastics without pre-tapping, reducing assembly time and tooling costs.
• Secure and efficient drive engagement with No. 2 Phillips pan head, providing reliable torque transfer and a low-profile finish.
• Optimized plastic retention through a 2.24mm thread pitch and blunt tip design, minimizing material stress and cracking.
• Full-length threading (M5 x 12mm) for maximum grip and uniform load distribution across the entire fastener length.
• Compliance with RoHS 3 and REACH regulations, guaranteeing safe use in consumer and industrial products without hazardous substances.
• Precision-matched drill bit size (No. 21/0.159") for easy installation and consistent performance in plastic assemblies.

Professional Applications & Engineering Value

These M5 tapping screws are specifically engineered for plastic assembly applications, where traditional fasteners may cause splitting or stripping. The 18-8 stainless steel material offers exceptional corrosion resistance, making them ideal for outdoor equipment, electronic enclosures, and automotive components exposed to moisture. The TRS thread-forming design creates strong, permanent threads in thermoplastics and soft metals without chips, ensuring vibration resistance and reduced loosening. With a Phillips pan head and fully threaded shank, they provide flush mounting and uniform clamping force, streamlining production in high-volume manufacturing while maintaining structural integrity.

Specification Summary & Compliance

This M5 x 12mm screw features a metric fully threaded design with a 2.24mm thread pitch and blunt tip for thread-forming (TRS type) applications in plastics.
