S-99397A628 Length 14 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP10 drive, reducing cam-out and tool wear for reliable installation
• Secure fastening in plastic materials thanks to the tri-lobe shank design that creates strong, vibration-resistant threads
• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in various environments
• High installation efficiency with fully threaded M3.12 design and 1.27mm pitch for quick, consistent engagement
• Reduced assembly complexity through thread-forming TRS technology that eliminates the need for pre-tapped holes
• Optimized plastic compatibility with blunt tip design that minimizes material stress and cracking during installation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global market acceptance

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws deliver exceptional engineering value in plastic assembly applications where material integrity and vibration resistance are critical. The thread forming design with tri-lobe shank cross-section creates precise, durable threads in plastic substrates without generating chips, eliminating contamination risks in sensitive assemblies. The Torx Plus IP10 drive system provides superior torque transmission compared to conventional drives, preventing stripping and ensuring consistent clamping force in high-volume production environments. With the M3.12 screw size and 14mm length, these fasteners are ideal for electronics enclosures, automotive trim components, and consumer products where reliable plastic-to-plastic or plastic-to-metal connections are essential. The combination of right-hand threading and 1.27mm pitch ensures quick installation while maintaining joint integrity under dynamic loads.
