**About Self Locking Counter Nuts:**
These nuts are manufactured from sheet metal and feature a unique design that allows them to flex under load and return to their original shape. This spring-like behavior ensures a secure fit in threaded areas, providing excellent vibration resistance. They can be tightened using an internal wrench, making them ideal for use in tight or hard-to-reach spaces.
