Hand nut

A nut, usually circular with serrated edges, is screwed down onto the minute hand.

To remove the nut, hold the minute hand as close to the nut as you can, and unscrew carefully. By holding the hand as near to the nut as possible you minimize the risk of bending it.

Some later clocks are fitted with slotted nuts for which the manufacturers had special tools. A pair of pliers will normally slip off these nuts, damaging the finish. A simple tool that fits most of these hand nuts is readily available. Hour hands should simply pull off.
