FASTENING TORQUES
FASTENING TORQUES AND RELATIVE PRE-LOADS FOR STANDARD CONNECTIONS
The values shown in the following table refer to standard fastenings, meaning regarding the coupled metric screws with
relative nut or with metal female screw.
Furthermore, the bodies to be fastened must be made of metal or sufficiently stiff not to require bushes interpositions or
spacers.
The coupling is always with lightly oiled or greased thread; alternatively, the type of requested thread brakes paste must
be shown.
The axial pre-loads, correlated to the fastening torque, are increased by 10% compared to the calculated value, to take into
account of the tolerance on the nominal moment of the torque and of the variation that the friction coefficient can suffer
from, from fastening to fastening.
(*) The shown metric screw is fine step.
