Filettature metriche ISO

Filettature metriche iso a profilo triangolare a passo grosso e passo fine

Si definisce filettatura un risalto a sezione costante, filetto, avvolto ad elica sulla superficie esterna di un elemento cilindrico (o conico), la vite, o sulla superficie interna di elemento analogo, la madrevite.

Dal punto di vista geometrico (ma anche costruttivo) gli elementi fondamentali per la definizione delle filettature sono:

la forma del profilo
il passo
il diametro nominale

Definizione di passo della filettatura.

Si definisce passo, la distanza, misurata in direzione assiale tra due punti omologhi di un filetto; essa è proporzionale all’altezza, H, del filetto.

Definizione di diametro nominale.

Il diametro nominale coincide (tranne che per le filettature gas) con il diametro esterno d (D), della vite (madrevite).
