Metal Garden Gate & Post - correct screws to use

[freddiemercurystwin]

Pop rivets would probably do.

I think I would tap the existing holes in the post to a suitable size (M6 or M8) and then use machine screws to fix the gate.

You can't tap it as the metal is too thin to make a thread, but as it is the top hinge, it's easily reachable from the top and the plastic top pops out.
I would drill it out to 6mm and put a bolt through with a nut on the inside. If a spanner is needed to hold the inside nut, better to put a length of string on it just incase it is dropped inside the post.

Then how are the self tappers holding?

Then how are the self tappers holding?

Self tappers have a much more course thread, which leaves much more metal in place to grip on when it's thin..

Self tappers only need a thin sheet to hold a screw.
