• Enhanced corrosion resistance with black zinc-plated steel construction for long-lasting performance in various environments
• Optimized installation efficiency with No. 2 Phillips drive that prevents cam-out and ensures secure fastening
• Maximum holding power from fully threaded shank design that provides consistent grip along the entire fastener length
• Reduced material stress with blunt tip design that gently forms threads without damaging plastic substrates
• Industry-standard reliability manufactured to ASME B18.6.3 specifications for consistent quality and performance
• Versatile application compatibility with standard pan head profile that accommodates various assembly requirements

Professional Applications & Engineering Value

These thread forming tapping screws are specifically engineered for plastic assembly applications where traditional fastening methods often cause material failure. The DST thread forming technology creates strong, permanent threads by displacing plastic material rather than cutting it, eliminating chips and reducing stress concentration. The black zinc-plated steel construction provides excellent corrosion protection while maintaining the mechanical strength needed for durable plastic fastening. With 19 threads per inch and 0.138" thread diameter, these screws deliver optimal thread engagement in plastic substrates, making them ideal for industrial assembly, electronic enclosures, and construction applications involving plastic components. The combination of Phillips pan head design and fully threaded shank ensures reliable installation and maximum pull-out resistance.

Specification Summary & Compliance

These No. 6 x 3/4" tapping screws feature precise thread forming design with 0.138" thread diameter and 19 threads per inch for consistent performance in plastic materials. Manufactured in compliance with ASME B18.6.3 specifications, ensuring dimensional accuracy and mechanical properties meet industry standards. The screws utilize right-hand threading and standard pan head profile with recommended No. 35 drill bit size (0.11" diameter) for proper installation. The black zinc-plated surface treatment provides corrosion resistance while maintaining the fastener's integrity in various environmental conditions.
