S-90380A304 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming capability with TRS tri-lobe shank design that creates strong, permanent threads in plastic materials
• Enhanced driving performance through Phillips No. 2 drive system that minimizes cam-out and improves installation efficiency
• Maximum holding power achieved through fully threaded design that provides consistent engagement along the entire fastener length
• Optimized plastic fastening with blunt tip and specific thread geometry that prevents material cracking and ensures secure connections
• Reliable dimensional consistency with precise No. 10 screw size and 14 threads per inch for predictable performance in assembly operations
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industrial applications

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are specifically engineered for plastic applications where traditional fastening methods often fail. The thread forming design with tri-lobe shank cross-section displaces plastic material rather than cutting it, creating stronger threads that resist stripping and back-out under vibration. The Phillips drive style ensures quick installation with standard tools while the fully threaded configuration provides maximum pull-out resistance. Ideal for industrial assembly of plastic components, enclosures, and structural elements, these screws eliminate the need for pre-tapped holes while maintaining material integrity through controlled stress distribution. The combination of zinc plating and precise dimensional control makes these No. 10 screws perfect for automotive, electronics, and consumer product manufacturing where reliability and corrosion protection are critical.

Specification Summary & Compliance

These thread forming screws feature precise inch system dimensions including No. 10 screw size, 1-3/4" length, 0.19" thread diameter, and 14 threads per inch. The TRS (Thread Rolling Screw) design with tri-lobe shank and blunt tip is optimized for use with No. 15 drill bit (0.18" diameter) in plastic materials. Manufactured to industry standards for tapping screw applications, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest industrial safety and substance restriction requirements for global manufacturing applications.
