• Complete thread engagement with fully threaded shank providing maximum grip length and distribution of stress
• Reduced material cracking risk featuring blunt tip design that displaces plastic material gradually during installation
• Reliable dimensional consistency manufactured to precise No. 10-16 thread specifications for uniform performance
• Industry compliance assurance meeting ASME B18.6.3 standards and RoHS 3 environmental regulations

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for plastic fastening applications where reliable, long-term performance is critical. The thread forming DST design eliminates the need for pre-tapped holes, creating strong mating threads directly in plastic substrates while minimizing stress concentration and material cracking. The fully threaded configuration ensures maximum engagement depth, providing superior pull-out resistance in thermoplastic and thermoset materials. The Phillips drive system combined with the pan head profile offers excellent torque transmission during installation, reducing operator fatigue in high-volume assembly operations. These industrial screws are ideal for electronics enclosures, automotive components, and consumer products where secure plastic fastening and regulatory compliance are essential requirements.
