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 separate tapping operations, creating strong, permanent threads in plastic substrates that resist loosening under vibration and thermal cycling. The Phillips drive system provides efficient installation with standard tools, while the pan head configuration offers excellent bearing surface for secure fastening without damaging delicate plastic surfaces. Ideal for industrial assembly, electronic enclosures, and construction applications involving plastic components, these screws deliver consistent performance with their right-hand threading and blunt tip that prevents material splitting during installation.

Specification Summary & Compliance

This No. 10 x 1" tapping screw features precision inch system measurements with a thread diameter of 0.19" and 16 threads per inch. Manufactured to exacting ASME B18.6.3 standards for dimensional accuracy and performance reliability. The product is fully RoHS 3 (2015/863/EU) compliant, ensuring environmental safety and regulatory adherence. The thread-forming tapping method and fully threaded design provide consistent fastening performance across the entire length, while the specified No. 27 drill bit size (0.144" diameter) ensures proper installation clearance for optimal thread engagement in plastic materials.
