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

Thanks you for the names.
You are quite correct I was trying to describe an anchor bolt the workman is back today so I have the name now brilliant
