Exceptions to this rule are all connections with screws that are not screw connections in
the real sense. This includes hose clips, cable glands, screw fittings, gas connections,
screws for circuit boards etc. Tighten these screw fittings as evenly as possible with a
much lower torque (hose clips 1 Nm, other screw fittings according to manufacturer
specifications).
Select the next lowest torque valid for the screw for mixed materials and special screws
such as relieved screws.
The basic friction coefficient is (screw fittings without lubrication) µk=µG=0.14. The
calculated values are valid for room temperature (T=20°C).
