Structural Steel and split/spring washers 1

[John Jones]

I'm reviewing EN 1090 and all related specifications relating to bolting. I have come to the conclusion that split/spring washers are not permitted by the standard yet I frequently come across structural steel with these washers.

I'm wondering has anyone here come across this before or does anyone have experience in the area.

As far as I know, these washers will actually result in faster loosening under load.
