S-99397A012 Length 4 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP5 drive, reducing cam-out and tool wear for reliable installation
• Excellent corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in demanding environments
• Vibration-resistant fastening through the Tri-Lobe shank design that creates secure threads in plastic materials
• Optimized for plastic applications with thread forming (TRS) design that eliminates chips and provides superior pull-out resistance
• Full thread engagement along the 4mm length ensures maximum holding power in shallow applications
• Precision blunt tip design allows for easier starting and prevents material damage during installation
• Environmental compliance with RoHS 3 and REACH regulations for use in regulated industries

Professional Applications & Engineering Value

These M1.59 metric tapping screws are engineered specifically for plastic fastening applications where reliability and precision are critical. The 18-8 stainless steel construction provides exceptional corrosion resistance, making these TRS thread forming screws ideal for electronics, automotive components, and medical devices exposed to harsh environments. The Tri-Lobe shank cross-section and 0.6mm thread pitch work together to displace plastic material during installation, creating strong, permanent threads without generating debris. The Torx Plus IP5 drive system ensures maximum torque transfer while minimizing stripping, allowing for consistent installation in high-volume production environments. These fully threaded screws with blunt tip design provide secure fastening in thin plastic sections where traditional fasteners might fail.

Specification Summary & Compliance

This precision M1.59 x 4mm tapping screw features a 0.6mm approximate thread pitch with fully threaded right-hand orientation and Tri-Lobe shank cross-section for optimal performance in plastic materials. Manufactured to precise dimensional standards with Torx Plus IP5 drive compatibility, these screws ensure consistent installation performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental standards for industrial applications.
