Nakrętki łożyskowe służą do osiowego ustalenia łożyska na wale. Nakrętki z gwintem metrycznym wykonywane są w wersji zwykłej (oznaczenie KM) lub w wersji lekkiej (KML) i są zabezpieczane przed samoczynnym odkręceniem z zastosowaniem podkładek zębatych MB lub MBL. Sposób montażu nakrętek podano tutaj>.
