S-99461A921 Length 6 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring longevity in humid or demanding environments.
• Efficient thread forming design (TRS type) creates strong, reliable threads in plastic without pre-tapping, reducing assembly steps.
• Optimized for plastic materials with a blunt tip and fully threaded shank to prevent cracking and ensure secure, vibration-resistant fastening.
• Easy installation and removal thanks to the Phillips No. 1 drive, providing good torque transfer and reducing cam-out risks.
• Consistent performance with a precise 0.98 mm pitch and M2.2 x 6mm dimensions, enabling repeatable, accurate assemblies.
• Compliance with environmental regulations including RoHS 3 and REACH, making them safe for various industries and export markets.
• Durable rounded pan head offers a low-profile finish and distributes clamping force evenly, protecting the plastic surface.

Professional Applications & Engineering Value

These M2.2 TRS tapping screws are specifically engineered for plastic assembly applications, where traditional fasteners may strip or cause material stress. The 18-8 stainless steel provides excellent resistance to rust and chemicals, ideal for electronics, automotive interiors, and consumer goods exposed to moisture. The thread forming (TRS) design displaces plastic material to form strong, permanent threads, eliminating the need for inserts and reducing part count. With a fully threaded shank and blunt tip, they minimize the risk of plastic cracking during installation, ensuring reliable connections in brittle polymers. The Phillips drive allows for quick, efficient driving with standard tools, enhancing production line speed while maintaining high torque capability.

Specification Summary & Compliance

This M2.2 x 6mm screw features a fully threaded shank with an approximate thread pitch of 0.98 mm, designed for use with a No. 50 drill bit (0.07" diameter). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they are free of hazardous substances. Manufactured to standard metric dimensions with a rounded pan head and Phillips No. 1 drive, these screws are suitable for high-volume, precision-driven industrial applications.
