sheet metal screws

Hello,
I'm looking to bulk purchase
#8 X 1/2" PHIL PAN SMS SCREW SS, PAINTED
Product Code: 33-022
Are these the ones that are slightly magnetic still? (400 series?)

Thanks,
Bill Arnold
Arnold Millwork Co.

To be clear, what I need are sheet metal screws that can hold on to a magnetic screw tip - Not that the screws themselves need to be magnetized!

Thanks,
Bill
