The NORD-LOCK bolt securing system uses geometry to safely lock bolted joints in the most critical applications.
This unique wedge-locking system offers the following advantages:
- Maximum safety
- Resists loosening caused by vibration and dynamic loads
- Ease of assembly and disassembly
- Locking function is not affected by lubrication
- Positive locking at low and high preload levels
- Controllable preload
- Same temperature characteristics as standard bolt/nut
Tension makes the bolt self-locking
The key is the difference in angles. Since the cam angle "α" is larger than the thread pitch "β", the pair of washers expand more than the corresponding pitch of the thread. NORD-LOCK washers positively lock the fastener in a joint which is subjected to extreme vibration or dynamic loads.
