Product Q&A

Q:Do these screws require a pre-drilled pilot hole?

No. The self-drilling point drills its own pilot hole, and the self-tapping thread cuts the mating thread in a single operation. No pre-drilling is needed, which saves significant installation time and labor.

Q:What material are the screws made of?

High-quality carbon steel (10B21), case hardened with a surface hardness of approx. 560 HV, giving excellent drilling performance and strong thread engagement.

Q:What surface finishes are available?

Common options: blue/white zinc plated, yellow zinc plated, black phosphate, and plain (self-color). Stainless steel (A2/A4) versions are also available on request.
