Half Lock Nut DIN439

Two half-lock nuts are typically used together to create a locked-in or jam nut configuration. By tightening them against each other in opposite directions, they effectively prevent the nut from loosening. This is a common technique used in applications where vibration or other factors might cause nuts to loosen.
