Stop Bolts GN 251.6

Product description

Information

Stop bolts with retaining magnet GN 251.6, in combination with the steel housing of the hex head screw, form a system that shields and strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface.

These stop bolts are suitable as workpiece stop, with the integrated magnet holding the workpiece in place.

After positioning, the stop bolt can be secured with the included lock nut.
