Tightening torques,
recommendations
The tightening torques in the following table are recommendations
when tightening bolts and nuts.
When torquing using a machine, for example, bolt runner, the tight-
ening torque should be reduced by approx. 5%.
For mild surfaces (hardness below 200 HB), washer shall be used
under both bolt head and nut. Alternatively, use flange bolt or flange
nut.
Tighten to the prescribed torque without stopping.
Recommended tightening torque may vary depending on surface
treatment. Certain combinations of nut and bolt require lubrication
according to the table below.
