Product Description
A technology in which the spring embedded in the nut absorbs vibration and loosening energy and converts it into a locking torque.
When tightening the nut, the spring diameter is enlarged, so it is easily tightened without frictional resistance.
When the nut is loosened, the spring is tightened automatically.
Prevents loosening from shock and vibration
Improvement of constructability due to ease of fastening work
Maintaining clamping force even in incomplete tightening
Can be used repeatedly without damaging screws
