Revolving ball knobs GN 319.5 can be utilized instead of revolving handles i.e. with handwheels.
The tapped shoulder allows the revolving ball knob to be mounted from the underside via a screw or bolt, which can then be easily mounted to sheet metal in a variety of thicknesses, flat bar, or castings, to create a quick cranking or turning mechanism.
Maximum heat resistance:  110°C (230°F).
For open ended wrenches see DIN 894.
