Setting bolts GN 251.6 with retaining magnets combine a magnet with a steel housing in the shape of a hex head screw to create a system that shields and strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface.

The setting bolts with retaining magnet can be used as workpiece stops that also hold the workpiece in position with the integrated magnet.

The locking nut (included) can be used to secure the stop screw after positioning.
