So a quick post before I head out to Tool Station for supplies.

The screws supplied with the order were these.

Maybe my expectations were too high, maybe they are the wrong ones, just ask the minister of health to explain.



Screws, seem to have a cutting groove.

The seal on the washer really distorts well when it hits the sheeting, so using them in the valleys, along with a plastic sealing cap, should be a great system.

Getting them in, that’s the challenge.





Trying to drive then straight through the sheeting results in a blunting off, like they were made of putty, almost instantly.

So maybe I got it wrong.





Mate Andy, in Tulsa, Oklahoma uses these for his sheeting work on his pole barns steel structure.





And also uses the same style screws that I have.




So maybe the screws I have are for timber structures, which mine is, but they really need to be done with a pilot hole, unless someone has other advice.

Off to work I go.
