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, the Tokyo Skytree boasts a modern design and is constructed with world-class technology. However, when building such a tall tower, it is essential to address the significant impact of strong winds and earthquake resistance, as well as to take adequate measures against rust due to its proximity to high-altitude clouds with high humidity. Therefore, we adopted our "Nord-Lock 254SMO washers." Tens of thousands of these washers in various sizes have been installed on the tower, and it has been confirmed that even after the terrifying earthquake with a magnitude of 9.03 that struck Tohoku on March 11, 2011, the equipment secured with our products remained safely in place.
