not sure you mean Rock Anchor anyway, do you mean an Anchor Bolt ?

a rock anchor is a steel bar with a large plate on end which holds together groundwork during excavations or rough rock/boulder walls.

An anchor bolt (ancle cerrojo or ancle barra) is fixed into concrete which will support heavy weights when something is fixed to it
