Can you use thses screws outside, as in do they rust, need to use on roof, thanks.
Hello,
The screws are corrosion resistance, but not corrosion proof. Meaning, that eventually, these screws can rust.
If you'rE using on a roof outside I would recommend opting for a screw that is corrosion proof, like a stainless steal screw.
Alternatively you might wish to consider a screw cover or perhaps applying a sealer over the screws to protect them from water.
I would advise contacting a competent tradeperson for further information and product recommendations.
Thanks for using Q&A. [DG]
