When Safety Really Matters
The Roller Coaster at the Tusenfryd Amusement Park outside Oslo, Norway, has 1 million bolted connections. Some are highly critical - and have no room for error.
To secure the bolted connections on this high vibration ride, Nord-Lock washers have been installed. Nord-Lock washers create a wedge-locking effect underneath the bolt head or nut, making it physically impossible for any loosening to occur. These safety washers are produced with attention to detail and precision. Every washer goes through quality controls throughout each production step. And then, every parameter is rigorously checked once again.
Because, for critical bolted connections, there is simply no room for compromise.
