S-99461A941 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming capability creates permanent, vibration-resistant threads in plastic materials without chips or debris.
• Excellent corrosion resistance from 18-8 stainless steel construction ensures long-term reliability in humid or demanding environments.
• Optimized drive engagement with Phillips No. 1 drive provides secure torque transmission and reduces cam-out risk during installation.
• Maximum holding power through full threading along the 8mm length delivers superior pull-out resistance in plastic assemblies.
• Streamlined installation process with blunt tip design prevents material splitting while maintaining precise alignment.
• Environmental compliance assurance meets RoHS 3 and REACH standards for use in regulated industries and international markets.
• Standardized metric dimensions (M3 x 8mm) ensure compatibility with existing tooling and design specifications.

Professional Applications & Engineering Value

These M3 thread forming screws are specifically engineered for plastic assembly applications where traditional fastening methods often cause material stress or failure. The TRS (Thread Rolling Screw) design with 1.34 mm thread pitch displaces plastic material during installation, creating stronger, more durable threads than cut threads. The 18-8 stainless steel construction provides exceptional corrosion resistance, making these Phillips pan head screws ideal for electronics enclosures, automotive components, and outdoor equipment where environmental exposure is a concern. The fully threaded design ensures consistent clamping force distribution, preventing loosening from vibration while the rounded pan head offers a finished appearance and sufficient bearing surface.

Specification Summary & Compliance

This metric tapping screw features M3 diameter with 8mm length and standard 1.34 mm thread pitch for precise engagement in plastic materials. Manufactured with Phillips No. 1 drive and pan head style (5.3mm diameter, 2.1mm height) for consistent installation performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications. Recommended for use with No. 41 drill bit (0.096" diameter) for optimal thread formation in plastic substrates.
