Hello Samuel87,
We would not recommend these screws for this use, unless you were fixing the steel to wood and the holes drilled had full clearance for the screws to pass through and grip the substrate. If we are fixing another material to the steel, please look instead at self-drilling or self-tapping screws.
Thank you for using Q&A
