S-90380A269 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Excellent holding power in plastic materials thanks to the TRS thread forming design and tri-lobe shank that displaces material without creating chips
• Simplified installation process with Phillips No. 1 drive providing reliable torque transfer and reduced cam-out risk
• Optimized for plastic assembly with fully threaded design and blunt tip for controlled penetration and minimal stress concentration
• Precise fit and consistent performance with standardized 0.099" thread diameter and 24 threads per inch ensuring reliable engagement
• Reduced preparation time with compatible No. 43 drill bit (0.089" diameter) for proper hole sizing in plastic components
• Compliance with international standards including RoHS 3 and REACH for safe use across global industrial applications

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications. The thread forming design creates strong, permanent threads in plastic materials without generating chips that could contaminate sensitive components. The tri-lobe shank cross-section provides superior resistance to vibration loosening while distributing stress evenly throughout the plastic substrate. This combination makes these self-tapping screws ideal for electronics enclosures, automotive plastic components, and consumer products where reliable fastening in plastic is critical. The Phillips drive system ensures compatibility with standard industrial tools while the fully threaded configuration maximizes pull-out strength across the entire engagement length.

Specification Summary & Compliance
