As the topic might suggest I am trying to find nails in the G.E.C.K., not railway spikes or something like that but a static of carpenter nails.
Some of the static wood objects have them, like the boarded up doors and the PBfences but I can't seem to find "loose ones".

I have been through the lists in the G.E.C.K. over and over and I guess that there probably isn't any such thing - but I am kind of living on the hope that I just have missed them:
they would look so good on my "hammered together" custom wasteland shelters. Floating boards that sticks to other boards by no visible means kind of ruins the look and feel at the moment.

I have never found a nail in the GECK, I think it's just too-small to be a normal clutter item. You could always re-tex a pencil, that would give you an object very close to a nail.

I just used the nif for the railway gun projectile to make a static object and used those. They were a bugger to place, being so small.

Thanks for the tips, no more using super glue for carpentry.
