S-99512A676 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T30 Torx drive design that prevents cam-out and allows for higher installation torque in plastic assemblies
• Enhanced corrosion resistance through Black-Oxide Steel construction, providing durable protection in various industrial environments
• Exceptional holding power achieved through the Tri-Lobe shank cross-section that creates strong, vibration-resistant threads in plastic materials
• Reduced installation stress with thread forming technology that displaces material without cutting, minimizing cracking in plastic components
• Optimized plastic fastening performance with blunt tip design and specific 0.234" drill bit compatibility for precise, secure installations
• Reliable thread engagement through fully threaded 1/4" diameter with 10 threads per inch, ensuring consistent fastening depth and pull-out resistance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing and global market acceptance

Professional Applications & Engineering Value

These TRS plastic tapping screws with thread forming capability are engineered specifically for challenging plastic assembly applications where traditional fasteners fail. The Tri-Lobe shank design creates permanent, high-strength threads in plastic substrates without generating chips, eliminating contamination risks in sensitive electronics or automotive components. The Black-Oxide Steel construction provides essential corrosion protection while maintaining the dimensional stability required for precision plastic fastening. With T30 Torx drive technology, manufacturers achieve consistent clamp load without tool slippage, reducing assembly line defects and rework costs. These fasteners are ideal for plastic enclosure assembly, automotive trim components, electrical housing, and consumer products where vibration resistance and long-term reliability are critical performance requirements.
