Electrical Connections (Earthing)

In this guide we’ll show you which Hilti Fastening on Steel (FoS) products to use for electrical connections.

S-BT threaded studs are our best practice recommendation for electrical connections, however it’s also possible to use X-BT threaded studs. For offshore applications we recommend studs in Stainless Steel (SS) material.
