S-92400A380 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic thanks to the tri-lobe shank design that displaces material to create a secure, vibration-resistant connection
• Corrosion-resistant zinc-plated steel construction ensures long-term durability and reliability in various industrial environments
• Effortless installation with the external hex head design, allowing for high torque application and quick assembly with standard tools
• Reliable thread-forming action (TRS type) creates strong, clean threads in plastic materials without pre-tapping, reducing assembly steps
• Full 1-inch threading provides maximum grip length for a stronger, more dependable fastening point in plastic assemblies
• Precise dimensional fit with a 0.216" thread diameter and 11 threads per inch, ensuring consistent performance and compatibility
• Compliance with major environmental regulations including RoHS 3 and REACH, making them suitable for use in regulated industries and global supply chains

Professional Applications & Engineering Value

These No. 12 zinc-plated steel TRS tapping screws are engineered specifically for plastic fastening applications where reliability is critical. The thread-forming TRS design eliminates the need for pre-tapped holes, significantly reducing assembly time and labor costs in high-volume production. The tri-lobe shank cross-section is crucial for plastic materials, as it displaces material without creating stress cracks, ensuring a tight, secure fit that resists loosening under vibration—a common failure point in automotive, electronics, and appliance manufacturing. The combination of zinc-plated steel for corrosion resistance and the external hex drive allows for efficient installation with common tools, making them ideal for automated assembly lines while maintaining joint integrity in demanding environments.
