Abstract
Una vite per coppie di serraggio di precisione, del tipo a testa lobata o con cava lobata (31), in cui ciascun lobo (37) è formato da una prima faccia (37') diretta in modo sostanzialmente circonferenziale e da due ulteriori facce sostanzialmente parallele (35, 36) dirette verso l'interno della vite; detta vite è dotata di una superficie di reazione (33) con una chiave di serraggio (32). Le porzioni di tale superficie di reazione (33) comprese fra due lobi adiacenti sono costituite ciascuna da una coppia di facce (38, 39) tra loro inclinate a formare un angolo concavo verso l'esterno della vite per costituire superficie di reazione con una chiave a profilo poligonale.
