S-99461A911 Length 5 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior thread-forming performance with TRS type design for reliable, vibration-resistant fastening in plastic materials without pre-drilled threads.
• Excellent corrosion resistance provided by 18-8 stainless steel construction, ensuring long-term durability in humid or demanding environments.
• Optimized drive engagement with No. 0 Phillips drive and pan head design for efficient installation and reduced cam-out during assembly.
• Full-length threading with 0.67mm pitch delivers maximum grip and distribution of clamping force across the entire fastener length.
• Blunt tip and thread-forming technology minimizes material stress cracking in plastics while creating strong, permanent threads.
• Precision metric dimensions (M1.6 x 5mm) ensure consistent fit and compatibility with standard plastic components and No. 55 drill bits.
• Environmental compliance assurance with RoHS 3 and REACH standards, meeting strict regulatory requirements for industrial applications.

Professional Applications & Engineering Value

These M1.6 tapping screws with TRS thread-forming technology are engineered specifically for plastic assembly applications where traditional fastening methods may cause material failure. The 18-8 stainless steel construction provides essential corrosion resistance for electronics enclosures, automotive trim, and consumer products exposed to moisture or chemicals. The fully threaded blunt tip design displaces plastic material without cutting, creating stronger threads that resist vibration loosening. With 0.67mm pitch and Phillips pan head configuration, these screws enable rapid installation in high-volume production while maintaining consistent clamping force. Ideal for securing plastic components in medical devices, electrical housings, and precision instruments where material integrity and regulatory compliance are critical.

Specification Summary & Compliance

This metric tapping screw features M1.6 diameter with 5mm length and standard thread pitch of 0.67mm. Manufactured with fully threaded shank and blunt tip optimized for thread-forming applications in plastics. The TRS (Thread Rolling Screw) type conforms to industry standards for plastic fastening. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in various industrial sectors. Compatible with No. 55 drill bit (0.052") for proper hole preparation in plastic materials.
