S-90380A306 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior vibration resistance through the Tri-Lobe shank design, preventing loosening in dynamic plastic assemblies
• Excellent pull-out resistance with thread-forming TRS technology that creates strong, permanent threads in plastic materials
• Enhanced corrosion protection with zinc-plated steel construction for extended service life in industrial environments
• Optimized installation efficiency with Phillips No. 2 drive that provides reliable torque transfer and prevents cam-out
• Complete material engagement through fully threaded design, ensuring maximum holding power along the entire 2-1/2" length
• Reduced installation stress with blunt tip design that minimizes cracking in plastic components during assembly
• Precise fitment with No. 15 drill bit compatibility (0.18" diameter) for clean, accurate hole preparation in plastic substrates

Professional Applications & Engineering Value

These No. 10 TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications where traditional fasteners often fail. The thread-forming Tri-Lobe design creates strong, permanent threads in plastic materials without generating chips, eliminating contamination concerns in sensitive assemblies. The zinc-plated steel construction provides essential corrosion resistance for industrial environments while maintaining the strength needed for demanding applications. With 14 TPI thread pitch and 0.19" thread diameter, these screws deliver optimal holding power in various plastic types, from thermoplastics to composite materials. The combination of Phillips drive and pan head design ensures reliable installation with standard tools, making them ideal for high-volume manufacturing environments where consistency and reliability are paramount.

Specification Summary & Compliance

These thread forming screws feature precise Class 2A thread tolerances with right-hand threading and standard pan head profile. The manufacturing process adheres to strict quality controls for dimensional accuracy, including 0.373" head diameter and 0.133" head height. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and industrial suitability. The TRS tapping screw type follows industry-standard specifications for plastic fastening applications, providing reliable performance and consistent results across manufacturing operations.
