Nuts
Nylon Insert Lock Nuts
The nylon ring in the crown grips the bolt thread and gives prevailing torque, so the nut stays where you tighten it. Nylon insert nuts suit continuous service up to roughly 120 °C; above that, use an all-metal lock nut. Replace after repeated removal.
- Nylon collar for prevailing torque
- Thin (DIN 985) and high (DIN 982) forms
- Not for service above roughly 120 °C
