Nord-Lock washers specialized for the construction industry! Introduction of a case study on their use in the Tokyo Skytree.
Here is an example of the use of Nord-Lock products in the Tokyo Skytree. Standing at 634 meters tall, the Tokyo Skytree is constructed with modern design and world-class technology. However, when building such a tall tower, it is necessary to take sufficient measures against strong winds, earthquakes, and rust, especially since it is close to clouds at high humidity. Therefore, our "Nord-Lock 254SMO washers" were adopted. Tens of thousands of these washers in various sizes have been installed on the tower, and it has been confirmed that equipment secured with these products remained safely fixed even after the terrifying magnitude 9.03 earthquake that struck Tohoku on March 11, 2011.
