S-99461A984 Length 25 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping
• Optimized installation speed with No. 2 Phillips drive providing secure tool engagement and reduced cam-out
• Enhanced material integrity through blunt tip design that displaces plastic without cracking or splitting
• Full threading capability ensures maximum grip length and uniform stress distribution along the entire fastener
• Regulatory compliance assurance with RoHS 3 and REACH compliance for environmental safety and global market acceptance
• Precision dimensional control with M5 metric sizing and 2.24mm pitch for consistent performance in plastic assemblies

Professional Applications & Engineering Value

These M5 thread forming screws deliver exceptional value in plastic fastening applications where material integrity and corrosion resistance are critical. The 18-8 stainless steel composition provides excellent durability against environmental factors, while the TRS (Thread Rolling Screw) design with 2.24mm pitch creates strong, vibration-resistant threads in thermoplastic materials without generating chips. The Phillips pan head with No. 2 drive ensures efficient installation in high-volume production environments, reducing assembly time and tool wear. Engineers specify these metric tapping screws for electronics enclosures, automotive plastic components, and consumer products where reliable plastic fastening solutions must withstand thermal cycling and mechanical stress without compromising the host material.

Specification Summary & Compliance

These M5 x 25mm fully threaded tapping screws feature standard metric dimensions with 2.24mm thread pitch and are manufactured to precise tolerances for consistent performance in plastic applications. The thread forming design eliminates the need for pre-tapped holes, while the blunt tip and rounded shank cross-section prevent material damage during installation. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted use in international markets. Recommended for use with No. 21 drill bit (0.159" diameter) for optimal thread engagement in plastic substrates.
