Screws: Do these ones exist?

[charliegolf]

I don't think it's ever been intended as weatherproofing, just for decorative and minimal protection, e.g. for hand tools.

It's just dipped in black paint. Nothing to do with Japan, the name was just western marketing as it looked a bit japanese!

I've got black japanned screws in my garage that have never been used but have turned rusty.

Wasn't it heated up and dipped in oil?

Thanks all...

Context: garden room really close to back fence... larch t n g on three sides, so I decided to use soffit on the back. Storm Darragh got between the cladding and the structure and ripped off a few sheets leaving the poly pins in place. In my defence, the edges weren't closed off, letting the wind in, cos the larch hadn't come. Hence the screw idea.
