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.

Não achei um termo técnico em PT para isso...

Example sentence(s):
  • All Saildrive propellers then have bosses which are ~ 3.125" long to ensure they pull up tight on the thrust face before the M16 / M18 nut starts to bind at the end of the thread.
