What gauge of metal can the screws drill through?

Standard Self Drilling Screws kits cover #2 and #3 drill points, which drill 1.0mm to 3.0mm sheet metal substrate. For heavier substrate (3.0mm to 6.0mm), use the #4 and #5 points stocked loose in the Screws for Metal range.

How do I identify which size in the kit I need?
