S-90380A196 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in various environments
• Excellent thread-forming capability through TRS tri-lobe design creates secure, vibration-resistant connections in plastic materials
• Optimized drive efficiency with Phillips No. 2 drive for reliable installation and reduced cam-out risk
• Maximum holding power achieved through full threading and 16 TPI pitch for superior grip in plastic assemblies
• Streamlined installation process with matching No. 23 drill bit size (0.154") for precise hole preparation
• Enhanced material displacement from tri-lobe shank cross-section reduces stress cracking in plastic components
• Compliance assurance with RoHS 3 and REACH regulations for safe use in industrial applications

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws are specifically engineered to address common challenges in plastic fastening applications. The TRS thread-forming technology with tri-lobe shank design eliminates the need for pre-tapped threads, creating strong, permanent threads in plastic materials while minimizing stress and potential cracking. The Phillips drive system ensures reliable installation with standard tools, while the zinc-plated finish provides essential corrosion protection for industrial environments. Ideal for plastic assembly in automotive components, electronic enclosures, and consumer products, these screws deliver consistent performance where traditional fasteners might strip or loosen over time. The combination of 0.164" thread diameter and 5/8" length offers optimal strength-to-size ratio for medium-duty plastic joining applications.

Specification Summary & Compliance

This tapping screw features precision thread forming with right-hand direction and fully threaded design. Manufactured to exacting standards with 0.164" thread diameter and 16 TPI thread pitch for consistent performance. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory compliance for industrial use. Designed for use with No. 23 drill bit (0.154" diameter) to achieve proper hole preparation in plastic materials.
