S-99397A267 Length 10 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the Tri-Lobe shank design that creates strong, vibration-resistant threads
• Enhanced corrosion resistance provided by the zinc-plated steel construction, ensuring long-term durability in various environments
• Reduced cam-out and increased torque transmission with the Torx Plus IP6/T6 drive, allowing for higher assembly precision and tool life
• Efficient thread forming action that eliminates the need for a pre-tapped hole, streamlining the installation process in plastic components
• Secure and flush mounting achieved with the standard pan head profile, providing a clean finish and consistent clamping force
• Reliable full-length threading ensures maximum grip along the entire 10mm length for robust fastening in plastic applications
• Simplified sourcing and compliance with RoHS 3 and REACH environmental regulations, meeting international standards for safe use

Professional Applications & Engineering Value

These M1.91 x 10mm thread forming screws are precision-engineered to address common challenges in plastic assembly, such as material cracking and stripped threads. The zinc-plated steel construction offers excellent strength-to-weight ratio, while the Tri-Lobe shank and 0.79mm pitch work together to displace plastic material without creating stress concentrations, effectively preventing part failure. The Torx Plus IP6/T6 drive ensures high torque transfer with minimal slippage, crucial for automated production lines where consistency is key. Ideal for electronics enclosures, automotive trim, and consumer goods, these TRS tapping screws provide a reliable, cost-effective solution for creating durable threads in plastic materials, enhancing product longevity and reducing assembly time.

Specification Summary & Compliance
