S-99512A665 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T15 Torx drive prevents cam-out and tool slippage during installation
• Enhanced corrosion resistance through Black-Oxide Steel construction ensures long-term durability in various environments
• Efficient plastic fastening with thread forming TRS design creates permanent, high-strength threads without pre-drilling
• Reduced installation stress thanks to Tri-Lobe shank cross-section that minimizes radial forces on plastic materials
• Consistent performance with fully threaded design and blunt tip for controlled penetration and secure fastening
• Regulatory compliance meeting RoHS 3 and REACH standards for safe use in industrial applications
• Optimized for plastic materials with precise No. 6 size and 19 threads per inch for reliable holding power

Professional Applications & Engineering Value

These Black-Oxide Steel TRS tapping screws are engineered specifically for plastic fastening applications where material integrity is critical. The thread forming design with Tri-Lobe shank cross-section displaces plastic material rather than cutting it, creating stronger threads that resist stripping and pull-out forces. The T15 Torx drive system ensures maximum torque transfer without damaging screw heads, making them ideal for high-volume production environments. These plastic tapping screws eliminate the need for threaded inserts in many applications, reducing assembly time and component costs while maintaining reliable fastening performance in electronic enclosures, automotive trim, consumer products, and industrial equipment where vibration resistance is essential.

Specification Summary & Compliance

These No. 6 x 3/8" plastic tapping screws feature precise inch system measurements with 0.138" thread diameter and 19 threads per inch for optimal engagement in plastic materials. The fully threaded design with right-hand thread direction and blunt tip ensures consistent performance. Manufactured to industry standards for thread forming screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
