S-90380A194 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastics without the need for pre-drilling, thanks to advanced TRS thread forming technology
• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term durability in various environments
• Efficient installation and reduced cam-out with the Phillips No. 2 drive, providing reliable torque transfer
• Secure, vibration-resistant fastening due to the tri-lobe shank design that creates strong threads in plastic materials
• Consistent performance and easy alignment with a fully threaded, blunt tip design for smooth insertion
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use
• Optimized for No. 23 drill bit compatibility (0.154" diameter), streamlining assembly processes in plastic applications

Professional Applications & Engineering Value

These No. 8 x 1/2" zinc-plated steel tapping screws are specifically engineered for plastic fastening applications, where traditional screws may strip or loosen over time. The TRS thread forming technology and tri-lobe shank cross-section displace material to create strong, permanent threads without generating chips, eliminating cleanup and improving joint integrity. The Phillips drive ensures quick installation with standard tools, while the fully threaded design and blunt tip provide consistent grip along the entire length, preventing material cracking in brittle plastics. Ideal for electronics enclosures, automotive trim, and consumer products, these screws deliver reliable performance in industrial assembly lines, reducing maintenance and enhancing product lifespan.

Specification Summary & Compliance

This tapping screw features a No. 8 size with 0.164" thread diameter and 16 threads per inch, adhering to standard inch measurements for precise fit. The pan head style with rounded profile offers a low-profile finish, while the right-hand thread direction and fully threaded construction ensure uniform engagement. Manufactured from zinc-plated steel, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming environmental safety and regulatory adherence for global supply chains.
