Frequently Asked Questions
Self-tapping screws tap their own threads but typically require a pre-drilled pilot hole in harder materials. Self-drilling screws feature a drill-shaped point that can drill their own hole and tap threads in a single operation.
Carbon steel (hardened C1022A) is ideal for high-strength requirements and fastening into metals. Stainless steel (SS304/SS316) provides superior corrosion resistance, making it perfect for outdoor, marine, or chemical environments.
