I thought clavado had something to do with nails–clavos–which it does. To hammer or drive in a nail is clavar. It can also mean to be stuck to something like having been nailed.

But what got me to thinking about clavado is when I saw it used at a swimming pool. The word clavado is used for the sport of diving. The idea is that you enter the water straight and fast like a nail going into a board.

It seems there are many figurative uses for the word clavar/clavado as well.
