Screws: Do these ones exist?

[charliegolf]

I need black, domed head screws, 30mm, with a nice big diameter head- like a built in washer. Does the collective wisdom have any ideas? Or... can you get black washers lol.

Use black spray paint

Where are they going to be used?

 

[charliegolf]

Outside, holding soffits I'm using as vertical cladding.

Google black pan head screws.

Check they're woodscrews if using into wood. Many that are available will be self-tappers intended for use into metal so will have a finer thread that may struggle to grip into wood.

Also check if they're corrosion resistant, or you'll have lots of brown streaks in a couple of years. Actually you probably will anyway, whatever they claim.

There are stainless nails with plastic caps specifically designed for cladding. Usually white but I'm sure other colours exist.

Normally there's a trim between soffit boards, you use stainless screws in the trim that is then covered by the next board, so the screws are completely hidden.

Black plastic head pins are often used where they will be seen , it it hollow interlocking or solid soffit?

Google black washers. Japanned screws to go with them ?

 

[Ivor Windybottom]

Japanned is just lacquered, it will rust almost immediately outdoors.

Happy to be corrected, but it never used to be .....


Previously, a black japanned finish was popular within an automotive finish due to its durability. Ironware was often japanned black for decorative reasons, and to also render it rustproof and therefore suitable for carrying water.

In the past, it was also used to protect metal objects such as sewing machines, hand planes and builders’ hardware.


And black washers exist. Use them a lot to secure items.

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.

We have differing history of it.

I was always of the belief it was specifically for outdoor use. Courtesy of my father. I still have 2 (very big) cardboard boxes of them in different sizes in my shed. The boxes are about dead but the screws haven't rusted.

I wonder if it's just different now to how it was. Changed spec, modern marketing etc

The other thing to note, if the soffit panels have a protective plastic film applied, peel it before you hammer the nail through it, because the little wisps of plastic left behind if you nail through it then peel take ages to clean up and look awful if you don't
