Rz is an indication of the surface quality. The value stands for the quality, Rz for the measuring method.

2,5 is the surface finish, probably measured in Ra (rather than Rz) and the 150 is the angle, though it should really say 30º

You've also got Rz 20 applied to a tapped hole which is nonsense.
