The Kwik-Lock nut may be used instead of the stand-

The Kwik-Lock nut cannot be used with cup wheels,
brushes, rubber backing pads, tuck pointing discs
(special discs used for joint repair) or with diamond

The arrow on the upper surface of the nut must be
within the index marks. If the arrow is not within
the index marks when the nut is tightened it will be
