Frequently Asked Questions About Self-Drilling Screws


Can self drilling screws go through thick steel?

Yes, depending on the screw size and tip type, they can handle light to medium-gauge steel.


Are self drilling screws the same as self tapping screws?

Not exactly—self drilling screws create their own hole, while self tapping screws need a pre-drilled hole.


Do I need special tools to use self drilling screws?

No, a standard drill or impact driver is sufficient for installation.


Are stainless steel self drilling screws rust-resistant?

Yes, stainless steel versions are suitable for applications exposed to moisture or outdoor environments.


Can I use self-drilling screws in wood?

While possible, they are primarily designed for metal and perform best in steel or aluminum.
