[Description]
This is a product of Nord-Lock, Sweden.Prevents loosening due to vibration.Because the wedge angle of the washer is set larger than the thread angle of the bolt, the tension of the bolt is increased by the loosening of the bolt by the vibration etc. because two washers are pushed apart, and loosening is prevented.
