FAQ

Q: Can this nut be reused?
A: Yes, but the nylon insert loses its locking effectiveness after several removals – new nuts are recommended for critical applications.

Q: What is the maximum temperature for this nut?
A: The nylon insert is rated up to +120°C; for higher temperatures, use all‑metal lock nuts (e.g., DIN 980).

Q: Does this nut require a washer?
A: Not necessary, but a flat washer can be used under the nut to distribute load if the bearing surface is soft.

Q: What bolt grade should this be used with?
A: Class 8 nuts are designed for property class 8.8 bolts.
