What are these nails/rods in the wall?

[MG_88]

We are currently renovating the surface of a room in a house built in 1955. When we removed the floor moldings, we discovered that there are metal rods in the wall, approximately 7-10cm apart, at "molding height." However, they are not all at the same height, varying by about a centimeter.

In some places, they are driven into the moldings, and in other places, they are bent to nail the molding in place.

Does anyone know what they are for? The house has a concrete/lightweight concrete frame.

Probably something that was used to attach the moldings at some point?

It looks like trim nails for concrete. They were probably used when the first trims were put in place, bent during some later wallpapering.

There's really nothing wrong with using them, but today I find it more convenient to drill and plug the concrete and then use screws.

Here is a lacquered variant.

However, I've never understood it, as I've never encountered a lacquered wire nail where the lacquer remains on the head (which is the only part you see) after you've hammered it in...

They are called "klippspik" https://www.gunnebofastening.se/produkter/spik/klippspik/klippspik/

They are called "klippspik" [link]

Rather "listspik" right?

Doesn't "klippspik" have a head to hold the wood detail slightly better?

Aha, you're probably right, then I learned something new today as well, thanks!
