Setting bolts GN251.2 are supplied with a hardened round head which serves as a firm end stop. In general these bolts are installed with a locknut.

By means of the knurled nut, the limit switch can be installed and taken out without having the need to loosen the setting bolt.

If the screw-in thread is earthed, the blue cable has to be connected to the mass.
