Free-cutting steel; circlips: polyamid (max. 100 °C)
The use of slot nuts with elastic stop rings has enormous cost advantages, in as much as securing plates and therefore also expensive milling work for a wedged slot are omitted.
The polyamide ring is resistant to petrol and oil.
Slot nuts with elastic stop rings can be used several times. They withstand the strongest vibrations and oscilations irrespective of the torque and are therefore usable as adjusting nuts.
