S-99512A210 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP10 drive that prevents cam-out and allows for higher installation torque
• Exceptional thread retention in plastic materials thanks to the TRS thread forming design that creates permanent, vibration-resistant threads
• Enhanced corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Optimal material displacement with tri-lobe shank cross-section that minimizes stress cracking in plastic components
• Complete thread engagement with fully threaded design and 20 TPI for maximum holding power across the entire fastener length
• Streamlined installation process with blunt tip and standardized pan head profile for consistent seating in pre-drilled holes
• Reliable performance compliance meeting RoHS 3 and REACH environmental standards for global manufacturing applications

Professional Applications & Engineering Value

These No. 4 x 1/4" zinc-plated steel TRS tapping screws are specifically engineered to address common challenges in plastic fastening applications where material integrity and long-term reliability are critical. The Torx Plus IP10 drive system delivers superior torque transfer while eliminating tool slippage that can damage plastic components during installation. The thread forming TRS design with tri-lobe shank creates strong, permanent threads in plastic substrates without generating chips, preventing contamination in sensitive assemblies. This makes them ideal for plastic assembly in electronics enclosures, automotive trim components, and consumer products where vibration resistance and consistent clamping force are essential. The combination of zinc-plated steel construction and full threading ensures durable performance in demanding industrial environments while maintaining compliance with international environmental standards.
