At the Spence copper mine in northern Chile, Nord-Lock's steel wedge-locking washers were implemented to secure machinery against bolt loosening caused by extreme vibrations. The mine, located in the Atacama Desert, has an annual output exceeding 250 million tons of copper.

In fall 2024, following a recommendation from a distributor, Spence replaced conventional washers on its gearless mill drive system with Nord-Lock washers. This change has eliminated bolt loosening issues, enhancing equipment operation and safety. Nord-Lock's washers are also deemed effective for use in other industries with less demanding requirements.
