Abstract
The hexagonal nuts of this product have a groove inside the nut into which a synthetic rubber ring can be inserted, and the synthetic rubber ring is fitted into this groove. When a bolt is screwed in, the bolt threads bite into the rubber ring fitted inside the nut, absorbing vibrations and preventing the nut from loosening. Because the synthetic rubber ring is isolated from the outside, it does not deteriorate and functions for a long period of time.
