The torque values reported in table 3 correspond to 80% of the yield stress limitIn each column two values are reported
of which the first refers to a friction coefficient of 0.10 and the second to a coefficient of 0.14. For our applications it
is advised to refer to the values corresponding to the coefficient of 0.14.
The couplings are to be considered orientative in that they can notably vary in measurement in relation to the type of
joint (rigid, semi-rigid, elastic etc.), the material on which the screws are tightened, the length of the screws, the type of
screwdriver employed for tightening (impulse, friction, continuous torque etc.), the condition of the edging finish etc.
If the joint is carried out with nuts or self locking rings, the torque value should be increased by approx. 15%
