ESSVE Spix can for example be used for the installation of steel joists/drywall studs, purlins, etc against concrete. An excellent supplement to firing nails.

Spix consists of a nail and an expander sleeve with a large collar. The sleeve is manufactured of zinc alloy, which gives good corrosion resistance.
The nail consists of hardened carbon steel with a bright zinc plated surface treatment.

Drill a hole, push Spix into the hole and hit the nail with a hammer. This gives easy and quick installation.
