Aanhaalmomenten voor schroefdraad verbindingen in Nm:
wrijvingscoefficient bij staal: 0.14 (nieuw, ongesmeerd)
wrijvingcoefficient bij RVS: 0.12 (nieuw, schoon en onbeschadigd)
De kolom „Cu” is voor elektro aansluitingen, zoals motoren. Dit is alleen bedoeld voor gebruik in uiterste nood. Raadpleeg als mogelijk altijd de originele datasheet voor de juiste aanhaalmomenten!
Tightening torques for threaded connections in Nm:
friction coefficient for steel: 0.14 (new, non-lubricated)
friction coefficient for stainless steel: 0.12 (new, clean and undamaged)
The „Cu” column is for electrical connections, such as motors. This is only intended for use in extreme emergency. If possible, always consult the original datasheet for the correct tightening torques!
