• Enhanced holding power in plastic due to the Tri-Lobe shank design, which reduces material stress and prevents loosening.
• Efficient thread forming technology creates strong, secure threads without pre-tapping, saving assembly time and labor costs.
• Easy installation with Phillips drive (No. 2 size) and blunt tip, allowing for straightforward use with standard tools and No. 32 drill bits.
• Full threading and right-hand direction provide consistent fastening depth and reliable performance in plastic assemblies.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global industry standards for hazardous substances.
• Durable pan head design offers a low-profile, rounded finish that resists snagging and improves aesthetic integration.

Professional Applications & Engineering Value

These No. 6 x 3/8" TRS tapping screws are specifically engineered for plastic fastening applications, addressing common issues like material cracking and weak thread retention. Made from 18-8 stainless steel, they resist rust and corrosion, making them ideal for harsh or outdoor environments. The thread forming method and Tri-Lobe shank cross-section displace plastic material gently, forming robust threads that minimize stress and prevent stripping. This design is perfect for assemblies in electronics, automotive components, and consumer goods, where vibration resistance and long-term integrity are critical. With a Phillips drive and compatibility with standard drill bits, these screws streamline installation, reducing assembly errors and enhancing productivity in industrial settings.

Specification Summary & Compliance

This product features a thread diameter of 0.138" with approximately 19 threads per inch, ensuring precise fit in plastic materials. It adheres to standard inch measurements and includes a pan head with a diameter of 0.27" and height of 0.097". The screws are fully threaded with a right-hand direction and blunt tip for controlled insertion. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming they are free from restricted hazardous substances and suitable for global industrial use.
