Abstract
The multiple advantages offered by the screw-nut tightening are affected by the possibility that in case of some pulsatory or vibratory loadings the auto-break condition not be satisfied. The present paper refers to a new type of nut, which, by a special construction, offers the possibility of considerable increasing of this condition and also to a series of tests performed in order to practical demonstrate this affirmation.
