Stop bolt loosening caused by vibrations for sure! Since it does not rely on friction, it can be used in conjunction with lubricants.
The "Nord-Lock Washer®" is a product that physically prevents the loosening of bolt connections by utilizing "axial force" rather than friction, featuring a washer shape consisting of two pieces. It is characterized by a wedge locking mechanism, allowing anyone to safely, easily, and reliably secure bolts and nuts, particularly effective against "rotation loosening" caused by vibrations. It can also be used in conjunction with lubricants during tightening. 【Features】 ■ Loosening prevention utilizing axial force ■ Can be used with lubricants as it does not rely on friction ■ Provides loosening prevention effects safely, easily, and reliably for anyone *For more details, please refer to the related links or feel free to contact us.
