S-90434A201 Length 7/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Exceptional holding power in plastic materials through advanced TRS thread forming technology that creates strong, permanent threads
• Reduced installation torque and cam-out risk with No. 2 Phillips drive design for efficient, secure fastening operations
• Flush surface finishing with 82° countersink angle and flat head profile for clean, professional-looking assemblies
• Enhanced vibration resistance from the Tri-Lobe shank design that prevents loosening under dynamic loads
• Reliable full-thread engagement across the entire 7/16" length for maximum pull-out strength in plastic applications
• Compliance with international environmental standards including RoHS 3 and REACH for global manufacturing compatibility

Professional Applications & Engineering Value

These No. 6 TRS tapping screws are specifically engineered for plastic fastening applications where traditional threading methods fail. The thread forming design displaces material rather than cutting it, creating stronger threads that won't strip or loosen under vibration. The zinc-plated steel construction provides essential corrosion protection while maintaining the necessary strength for industrial applications. With their Tri-Lobe shank cross-section, these screws require lower installation torque while delivering higher resistance to back-out, making them ideal for plastic assemblies in automotive components, electronics enclosures, and consumer products where reliability is critical. The Phillips drive ensures compatibility with standard industrial tools, streamlining production processes.

Specification Summary & Compliance

These thread forming screws feature precise 0.138" thread diameter with 19 threads per inch and standard Class 2A tolerance for consistent performance. The TRS (Thread Rolling Screw) design follows industry-standard thread forming specifications for plastic materials. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications. The 82° countersink angle matches standard drill bit preparations for proper seating in plastic components.
