S-99461A977 Length 10 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in humid or demanding environments.
• Efficient thread forming with TRS design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time.
• Optimal material displacement from the blunt tip design minimizes stress cracking in plastics for more reliable fastening.
• Secure drive engagement with No. 2 Phillips head ensures consistent torque application and reduces cam-out during installation.
• Full threading along the 10mm length provides maximum grip and holding power throughout the entire engagement area.
• Precision metric sizing with M5 diameter and 2.24mm pitch ensures perfect compatibility with standard plastic components and drill sizes.
• Environmental compliance meets RoHS 3 and REACH standards for use in regulated industrial applications worldwide.

Professional Applications & Engineering Value

These M5 thread forming screws are specifically engineered for plastic assembly applications where traditional fastening methods can cause material failure. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining sufficient ductility for the thread forming process. The TRS (Thread Rolling Screw) design with 2.24mm pitch creates strong, load-bearing threads in plastic substrates through material displacement rather than cutting, eliminating chips and reducing stress concentration. The blunt tip and fully threaded configuration ensure smooth material flow during installation, preventing plastic cracking while maximizing pull-out strength. Ideal for plastic fastening in electronics enclosures, automotive components, and industrial equipment where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These metric M5 tapping screws feature standard thread forming (TRS) design with 2.24mm pitch and fully threaded configuration. Manufactured from 18-8 stainless steel with No. 2 Phillips drive and pan head style. Compatible with No. 21 drill bit (0.159") for proper hole preparation in plastic materials. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for use in industrial applications requiring hazardous substance restrictions.
