[Healeys] Spring washers don't work !

[Oudesluys]

Split spring washers should not be used on its own really, especially 
with soft(ish) materials like aluminium or cast iron.
It is best to use a plain washer on the material, then a spring washer 
followed by the nut or bolt.
I  prefer to use the non split spring steel washers, either domed or 
cupped. In critical applications I always use Locktite, lock wire or a 
double nut.
