S-90380A318 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention with TRS thread forming design that creates strong, vibration-resistant threads without chips or debris
• Enhanced corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Optimized drive efficiency with No. 3 Phillips head providing reliable torque transfer and reduced cam-out risk
• Maximum holding power achieved through fully threaded design and tri-lobe shank that ensures secure fastening in plastic materials
• Precision installation with standardized 1/4" diameter and 10 threads per inch for consistent performance across applications
• Reduced assembly stress thanks to blunt tip design that minimizes material cracking during installation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in various industrial sectors

Professional Applications & Engineering Value

These 1/4" TRS tapping screws deliver exceptional engineering value in plastic fastening applications where material integrity and long-term reliability are critical. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for demanding industrial environments. The unique tri-lobe shank design combined with thread forming technology creates secure, permanent threads in plastic substrates without generating chips that could compromise electrical components or sensitive mechanisms. This makes them ideal for plastic assembly in automotive trim, electronic enclosures, and consumer products where vibration resistance and consistent clamping force are essential. The fully threaded configuration ensures maximum engagement along the entire fastener length, distributing stress evenly and preventing material fatigue in plastic components.

Specification Summary & Compliance

These precision tapping screws feature a 1/4" thread diameter with 10 threads per inch and Class 2A thread tolerances for consistent performance. The TRS (Thread Rolling Screw) design follows industry-standard thread forming specifications with a tri-lobe shank cross-section that displaces material rather than cutting it. Manufacturing complies with RoHS 3 (2015/863/EU) regulations for hazardous substance restrictions and REACH (EC 1907/2006) standards for chemical safety, ensuring environmental compliance for industrial applications worldwide.
