| | | distância de aperto | Explanation:
Acredito ser a distância que a hélice deve se deslocar no eixo da posição inicial de encosto até a posição final após o aperto final.
Já que o eixo é cônico, esta distância vai determinar os esforços do aperto. Apertar demais, vai trincar a hélice, apertar pouco, vai ficar solta.
