To reduce the risk of settlement of the material and the
associated reduction in the preloading force if the hardness of the
surface supporting the bolt head or nut is lower than 200 HB, a
washer should be fitted under the bolt head and nut. This is not
applicable if flanged bolts or flanged nuts are used.
When tightening is carried out, the specified torque should be ap-
plied without pause, to ensure that the torque wrench will not be
tripped by the static friction before the joint has been tightened to
the specified torque.
