One for the oldies...Black jappaned screws

[Leesparkykent]

I'm wondering what was the benefit of using these?

 

[Darkwood]

Benefits were simply aesthetic - It was to suit black japanned metal work which was popular, it was a dull matt black finish to compliment ironworks and furniture wear of the day.

Very little rust.

 

[Leclanche]

I remember using them on SWA clips again just to blend in with the black cleats, seemed to have a soft head & easily slipped off with the cross head driver, sometimes having to finish off with a
persuasive tap with the hammer. I also remember using them on small pyro clips...distant memories now...

and rem.not everything was fixed with countersunk screws. black japanned screws were more suited for some applications.

I've seen them on back boxes and read a thread on here where they where specified on a job for fixing back boxes....I can't see what the benefit would be.

Always use round heads on back boxes although you don't see jap black round heads anymore because back boxes do not have countersunk holes, attention to detail and all that.

Before anyone catches me out I use c/sunk on plastic back boxes

mmmm! Black japs. Used 'em on pyro, by the thousand, basically to prevent rust and look well. Things moved onto to brass roundheads and then pozidrives...but 'Black Japs'....I'd lay odds such a term involves racial prejudice these days.

Always used brass round heads on MI, still do.

Probably banned 'em for bleedin' H+S reasons, then.

@Leesparkykent as has been mentioned, they were specified because of the head been round and unlikely to catch on cables, they were massed produced and cheap to boot, any roundhead screw would have done tbh if the question was asked.

Ah well then.....another reason for an addition to the 18th edition. It's as good as most of the others.
