Information

Nut: Steel, zinc plated, blue passivated, tensile strength 500 N/mm2

 

GN 1804.1 slotted spanner lock nuts are self-locking because of the polyamide insert. They can therefore also be used as a setting nut and may be used more than once.
The thread series corresponds to DIN 981 roller bearing slotted spanner nuts.
For our selection of hook spanner wrenches for use with these components, see Section 16 - Tools, particularly DIN 1810A hook spanner wrenches with nose end.
