Citroen type spring washer, M5 x 16 (pack of 6)
1 x Pack of 6 "Rondelle" type shake proof washers widely used on most Citroen models from the late 1960's.
These suit M5 screws and bolts and have an outside diameter of 16mm.
Price is per pack of 6 washers.
There are some reproductions on the market which are badly made from a very soft material which is obviously no good for a spring type washer! Beware of these as they are no good at all.
