Spanner. Kirlian photograph of a spanner with a metal washer (upper left) and a nut (to its right) showing the electromagnetic discharge around their edges. This luminous discharge is the result of high-energy interactions between the objects and a powerful applied electric field. Spanners are used to tighten nuts,which hold objects together firmly. Washers are placed underneath nuts to prevent the nut damaging the object it is holding | |
