S-90485A429 Length 6 mm Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel construction ensures long-term reliability in humid or demanding industrial environments.
• TRS thread forming design creates strong, permanent threads in plastic without pre-tapping, reducing assembly time and tooling costs.
• Phillips No. 1 drive and flat head with 90° countersink provides flush, secure installation and prevents head stripping during torque application.
• Fully threaded M2.5 x 6mm body delivers maximum grip and holding power in plastic materials for enhanced joint integrity.
• Precision-metric dimensions and blunt tip ensure easy alignment and prevent material cracking during installation.
• Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in global industrial supply chains.
• Optimized for plastic substrates with recommended No. 45 drill bit (0.082") for perfect fit and reduced stress concentration.

Professional Applications & Engineering Value

These M2.5 tapping screws are specifically engineered to address common challenges in plastic assembly, where traditional fasteners can cause cracking or strip threads. The 18-8 stainless steel material provides excellent corrosion resistance for outdoor equipment, electronic enclosures, and automotive components exposed to moisture. The TRS thread forming technology displaces plastic material during installation, creating zero-clearance threads that resist vibration loosening and maintain clamp force. With a Phillips flat head and standard countersink profile, these screws sit flush with surfaces while the fully threaded design ensures consistent load distribution. Ideal for plastic fastening in consumer electronics, industrial machinery, and medical devices where reliability and regulatory compliance are critical.

Specification Summary & Compliance

This metric screw features M2.5 size with 6mm length, fully threaded right-hand design with approximate 1.12mm pitch, and standard flat head profile. Manufactured to precise dimensional tolerances for consistent performance in plastic applications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restriction of hazardous substances and safe industrial use. Recommended for use with No. 45 drill bit (0.082") and 90° countersink angle for optimal installation in plastic materials.
