Le rondelle spezzate non servono a un cazzo.
Non lo dico io, lo disse la NASA nel lontano 1990:
«“The typical helical spring washer … serves as a spring while the bolt is being tightened. However, the washer is normally flat by the time the bolt is fully torqued. At this time it is equivalent to a solid flat washer, and its locking ability is nonexistent. In summary, a lockwasher of this type is USELESS FOR LOCKING.»

in reply to Il Roccio • • •La parte sotto è un espositore recuperato in farmacia, al quale ho ricostruito i 3 cassetti in legno.
I cassettini in alto sono roba da dattilo trovata in discarica.
Le rondelle sono messe dentro a pacchetti di sigarette vuoti.
