Tightening torques and initial-tensioning forces

The tightening torques apply to friction coefficients of μ

total

= 0.14. The friction

coefficient μ

total

= 0.14 applies here to lightly oiled steel bolts, blackannealed or phospatised

and dry, cut mating threads in steel or cast iron. Lubricants which alter the friction coefficient
must not be used and may overload the screw connection.
