A Counter Nut is suitable for use as a standalone fastener in light-duty assemblies, but is generally used in conjunction with a standard nut to assure tightness in heavy-duty applications.
Self Locking Counter Nuts are available in diameters of between M4 and M27. Nut widths range from 7.00mm up to 41.00mm across flats.
