S-90485A421 Length 6 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.
• Efficient thread-forming design (TRS type) creates strong, permanent threads in plastics without pre-tapping, reducing assembly time and tooling costs.
• Flush mounting capability with standard flat head and 90° countersink angle for a smooth, professional finish in plastic assemblies.
• Secure, slip-resistant drive using Phillips No. 1 for consistent torque application and reduced cam-out during installation.
• Full threading along the 6mm length provides maximum grip and uniform stress distribution in plastic materials.
• Environmental compliance assurance with RoHS 3 and REACH, making them suitable for regulated industries and global supply chains.
• Precision metric sizing (M2.2 x 6mm) ensures exact fit and interchangeability in international engineering projects.

Professional Applications & Engineering Value

These M2.2 TRS thread-forming screws are engineered specifically for plastic assembly applications, where their 18-8 stainless steel composition resists oxidation and chemical exposure. The flat head with 90° countersink sits flush to prevent snagging and improve aesthetics in consumer electronics, automotive trim, and appliance housings. The thread forming (tapping) action displaces material without cutting, creating zero chip debris and stronger thread engagement than conventional machine screws. This design eliminates the need for separate tapping operations and reduces the risk of plastic cracking, making them ideal for high-volume production lines. Combined with Phillips No. 1 drive compatibility, they offer reliable fastening in tight spaces where vibration resistance and repeatability are critical.

Specification Summary & Compliance

This M2.2 x 6mm screw features a fully threaded shank with 0.98mm pitch and blunt tip for controlled penetration in plastics. Manufactured to standard metric dimensions with a 3.8mm head diameter and 1.2mm head height. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they are free of restricted hazardous substances. Recommended for use with No. 50 drill bit (0.07") for optimal performance in plastic materials.
