GN 319.2 tapped shoulder type revolving ball knobs can be utilized instead of other 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.
