S-99397A018 Length 6 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Enhanced torque transmission and reduced cam-out risk with Torx Plus IP5 drive for reliable, efficient installation
• Excellent holding power in plastics due to the tri-lobe shank design that creates secure, vibration-resistant threads
• Reduced material cracking with blunt tip and thread forming (TRS) design for damage-free assembly in plastic components
• Full-length threading ensures maximum grip and uniform stress distribution along the entire fastener length
• Precise dimensional accuracy with metric sizing (M1.59 x 6mm) for consistent fit and repeatable assembly results
• Compliance with environmental regulations including RoHS 3 and REACH for safe use in regulated industries

Professional Applications & Engineering Value

This M1.59 thread forming tapping screw delivers exceptional engineering value in plastic assembly applications where material integrity is critical. The 18-8 stainless steel construction provides reliable corrosion resistance, while the tri-lobe shank cross-section and TRS thread forming design displace plastic material to create strong, permanent threads without tapping pre-drills. This eliminates chip formation and reduces stress concentration, preventing cracking in brittle plastics. The Torx Plus IP5 drive enables higher torque application with superior tool engagement, minimizing strip-out risks during high-volume production. Fully threaded with a blunt tip, it ensures maximum pull-out resistance in electronic enclosures, automotive trim, and consumer products where vibration resistance and precision fastening are paramount.

Specification Summary & Compliance

This metric tapping screw features M1.59 diameter with 6mm length and fully threaded right-hand orientation with approximate 0.6mm pitch. Manufactured to TRS type standards for thread forming applications in plastics, it maintains precise dimensional tolerances for consistent performance. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial applications worldwide.
