Nylon Insert Lock Nut
A hex nut with a nylon ring that grips the bolt thread, so it stays tight under vibration. The ring is compressed as the nut is tightened, creating friction that resists loosening. Install with a standard wrench or socket. Used on machinery, vehicles and equipment that vibrate.

Questions
Why is there no hot-dip galvanized option below M8?
The zinc layer is too thick for smaller threads, so hot-dip galvanizing starts at M8.
Low or high nylon insert lock nut?
This low version is lighter but carries less load. The high version (DIN 982) is full height and carries the full load of a matching bolt.
