Tightening by hand, the FFFT method
• After tightening the nut by hand, draw a line on one side of
the nut (A) and continue the line all the way to the nut of the
connector (B). After this, tighten by the number of turns (FFFT)
mentioned in the table. Then, mark the nut of the connector,
opposite the marking that has moved (C).
• The markings have a couple of functions. They function as fast quality inspectors, making sure that the
connectors are properly tightened, and the other line in the connector functions as a mark, indicating that
the nut has been tightened by the right amount when the connector has been removed.
• This method is slower than the torque method, but it rules out the need for special tools and problems
related to the combination of different types of surfaces. With this method, you get a visual confirmation
that the connector is tight.
