S-90485A483 Length 25 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 chemically exposed environments
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and tooling costs
• Precise 2.24mm pitch threading delivers optimal grip and load distribution, preventing material stripping in plastic applications
• Streamlined installation with Phillips No. 3 drive and standard flat head profile, providing secure tool engagement and flush finishing
• Enhanced material compatibility with 90° countersink angle, allowing clean seating in plastic components without surface damage
• Full 25mm threading length maximizes holding power across the entire fastener engagement area
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting strict industrial environmental and safety requirements

Professional Applications & Engineering Value

These M5 TRS thread forming screws are specifically engineered for plastic fastening applications where traditional threaded fasteners would fail. The 18-8 stainless steel composition provides exceptional corrosion resistance, making them ideal for outdoor equipment, electronic enclosures, and automotive components exposed to moisture. The thread forming design displaces plastic material rather than cutting it, creating zero clearance fit that resists vibration loosening and maintains joint integrity. With 2.24mm pitch and fully threaded configuration, these metric tapping screws distribute stress evenly across plastic substrates, preventing cracking and material fatigue. The combination of Phillips drive and flat head profile ensures quick installation while maintaining a clean, flush surface finish critical for aesthetic components and safety applications.

Specification Summary & Compliance

This M5 x 25mm TRS tapping screw features fully threaded configuration with 2.24mm pitch and standard metric dimensions. The fastener maintains precise thread forming specifications for plastic applications, requiring No. 21 drill bit (0.159") for proper installation. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. The 90° countersink angle and flat head design provide optimal seating in plastic materials while the Phillips No. 3 drive offers reliable installation torque transmission.
