What is the technical name of those screws used to join together two sheets of stainless steel? They typically have a very sharp thread which grip the metal together

Do you simply mean self-tapping screws, or is it something more subtle that I don't know about?

I have seen some that have a sharp and machined tip; they seemed specially made to deal with SS sheet.

Tek-screws? They have a sort of vestigial drill-bit on the end so you don't need to drill holes. I helped clad an industrial unit a few years ago and if I remember rightly we were screwing them through the powder-coated cladding sheet and straight into the steel frame, with no drilling.
I actually have a few in my damage-control bag on the boat, just in case I ever need to screw a bunk board over a missing port or hatch
. Don't want to be messing about with pilot holes in the GRP under those circumstances!Pete

I learned something new today! Tek screws sound like a gift from the gods.

They're certainly perfect for steel roofing sheets onto steel frames. That kind come with a washer attached, with a rubber face to seal the hole. You put a socket driver in your cordless drill, and just dap them in wherever needed, couple of seconds each.

You're always full of great ideas, Pete. I have some in the garage, spares from doing a stable roof last year. Now there will be a handful on the boat. Thanks:encouragement:

That's a variety of them, yes. They're different to the roofing screws I was thinking of, but the part that makes them a Tek screw is the odd-looking tip which these have.
Countersunk is probably not what you want for sheet metal, I assume those are intended for attaching wooden facing onto a metal structure.

A2 is too soft to drill into stainless steel sheet.I don't think those on ebay are meant for that.

For thin sheet stitching screws are effective. The link describes some stainless ones. They have a coarse thread to spread the load.

In the double glazing industry they are known as 'Baypole' screws.
