S-99397A185 Length 5 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in humid or demanding industrial environments.
• Enhanced torque transmission and reduced cam-out thanks to the Torx Plus IP6 drive, allowing for higher tightening precision and tool longevity.
• Excellent thread retention in plastic materials due to the tri-lobe shank design, which forms strong, reliable threads without pre-tapping.
• Optimized 0.91mm pitch provides maximum holding power and vibration resistance in plastic assemblies.
• Full threading and blunt tip ensure easy starting and consistent engagement, minimizing material stress and cracking.
• Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use across global industrial applications.
• Compact 5mm length and 4mm head diameter offer space-saving solutions for precision electronic and plastic component fastening.

Professional Applications & Engineering Value

These M2.26 TRS thread forming screws are specifically engineered to address common challenges in plastic fastening, such as material cracking, thread stripping, and loosening under vibration. The 18-8 stainless steel material provides excellent strength and corrosion resistance, while the tri-lobe shank cross-section displaces plastic material during installation to create robust, permanent threads without the need for pre-drilled threads. This design minimizes stress concentration, reducing the risk of failure in sensitive plastic applications like electronics enclosures, automotive components, and consumer appliances. Combined with the Torx Plus T6 drive, these screws deliver reliable, high-torque performance for automated assembly lines, ensuring consistent clamping force and reduced assembly time.
