A friction-independent locking washer!
Our company handles the "Nord-Lock Washer," a type of locking washer. Utilizing a wedge-shaped cam, it relies on tension rather than friction resistance. We offer SC materials (M3 to M130) and SUS materials (M3 to M80), as well as our new product, the Nord-Lock Washer X series. Individual sales are also available! This product is useful when true safety in bolt fastening is required. 【Features】 ■ Maintains high axial force, ensuring reliable fastening function ■ Quick and easy installation and removal with standard tools ■ Allows the use of lubricants on the fastening body since it does not rely on friction ■ Achieves more precise axial force management due to clear and consistent friction conditions ■ Can be used under the same temperature conditions as standard bolts/nuts, etc. *For more details, please download the PDF or feel free to contact us.

basic information
【Test Results】 ■ Nord-Lock wedge locking washers have undergone rigorous testing by certification bodies and independent research institutions, proving their performance. ■ In the Junker vibration test, which complies with DIN65151, the bolts and nuts are subjected to vibrations in the parallel direction (shear direction), which are known to cause loosening. During this time, the bolt clamping force is continuously measured. Even in this harsh environment, Nord-Lock washers consistently demonstrate a higher loosening prevention effect compared to general locking products. *For more details, please download the PDF or feel free to contact us.
