Professional Applications & Engineering Value

These No. 14 x 1/2" Phillips Pan Head tapping screws are specifically engineered for plastic fastening applications where reliability and material integrity are paramount. The DST thread-forming technology eliminates the need for pre-tapped holes while creating strong, load-bearing threads that resist loosening under vibration. The black zinc-plated steel construction provides essential corrosion protection for industrial environments, while the fully threaded design ensures consistent clamping force along the entire fastener length. The combination of 0.242" thread diameter and 15 TPI pitch delivers optimal thread engagement in various plastic materials, from thermoplastics to composite assemblies. These tapping screws solve common plastic fastening challenges by preventing material stress concentration and reducing installation time through their self-tapping capability.

Specification Summary & Compliance

These thread forming screws feature precise dimensional specifications including 0.242" thread diameter, 15 TPI thread pitch, and 1/2" length with full threading. The manufacturing process adheres to ASME B18.6.3 standards for dimensional accuracy and performance requirements. The black zinc-plated surface treatment provides corrosion resistance while maintaining compatibility with industrial applications. The screws are designed for use with No. 7 drill bits (0.201" diameter) for proper hole preparation in plastic materials, ensuring optimal thread formation and holding strength.
