Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws are engineered specifically for plastic fastening applications where material integrity is critical. The DST thread forming technology creates permanent, high-retention threads in plastic substrates without generating chips, eliminating contamination risks in sensitive assemblies. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the fully threaded design ensures maximum holding power across the entire fastener length. The combination of 32 TPI threading and blunt tip prevents plastic cracking during installation, making these screws ideal for electronic enclosures, automotive trim, consumer products, and other precision plastic assemblies requiring reliable, vibration-resistant fastening solutions.
