I see many different types, there. Thanks for that.

I guess I should have been a little more specific, in that I was looking
for a self-tapping screw that would easily penetrate soft or low-carbon
steel, like the one's I used on the Limey motorcycle frame. Is that a
special type, or do they all do that? I'm looking to use the screws to
punch through and lock up the louvre adj linkage on a forced air heat
register, which is stamped steel. Thnx.

nb

There are many different styles of Tek screws. Some have little ears
above the drill bit to widen a hole through wood when wood is being
fastened to metal beams. If you search Tek or drill point screws,
you'll probably come across the exact screw you have used.
