Threadlocker is a standard industrial product in both Brazilian and American manufacturing. In Brazil, it's commonly used in automotive repair shops and industrial maintenance. The product is typically referenced by brand names like 'Loctite' (pronounced 'Loctáite' in Portuguese), which has become somewhat genericized in technical contexts, similar to how 'band-aid' is used generically in English.
