Tightening torques for male connectors as per MTN 5183-3
This works standard applies to male connectors DIN 2353, row L with screwed plug DIN 3852 model A
(sealed by sealing ring DIN 7603-Cu).
Tightening torques M are given for male connectors made of steel (St) with surface protected by a phosphate
A
coating and oiled or galvanised.
Threads and mating faces beneath heads must be coated with engine oil prior to assembly.
When tightening manually (tightening specifications), an assembly tolerance of +10% of the table values is
permitted for unavoidable deviations of the tightening torque from the table value during the tightening process - e.g.
resulting from inaccurate readings and overtightening during assembly.
