A washer that is easy to install and remove, and does not loosen even under intense vibrations.
The "Nord-Lock Washer" is a locking washer with a wedge shape on the inside and radial ribs on the outside. By combining Nord-Lock Washers, a powerful effect is achieved. When the bolt is tightened, the ribs bite into the clamped object and the nut, absorbing any loosening of the bolt and nut due to the wedge effect, which actually increases the tension of the bolt. Additionally, the angle of the inner wedge is designed to be larger than the thread lead angle, ensuring that the nut does not loosen by more than one thread even under severe vibrations. 【Product Lineup】 ■ Nord-Lock Washer SC Material NL8 ■ Nord-Lock Washer SC Material NL10 ■ Nord-Lock Washer SC Material NL18 ■ Nord-Lock Washer SC Material NL27 ■ Nord-Lock Washer SC Material NL33, etc. *Please feel free to contact us for more details.
