How effective are Nord-Lock wedge-locking washers against bolt loosening?
The wedge-locking principle uses tension rather than friction to secure the bolted joint in place. All bolted connections will start to loosen during its life cycle. Nord-Lock wedge-locking principle does not only prevent loosening but actually stretches the bolt and prohibits further rotation.
Wedge-locking washers require a higher than average upfront cost than other fasteners, however, they are also the most suitable for critical bolted joints facing vibration and dynamic loads and can be reused – leading to lower long-term costs.
