Ultra-polished lock nut series finished with precision grinding on all end faces, back faces, and outer surfaces.
Ideal for high-speed, high-rotation machine tool spindles and pole screw support bearings. The screw surface, as well as the outer diameter surface and back surface, are finished with precision grinding, which also improves balance quality. <Features> ■ Precision grinding on the screw surface, end face, back surface, and outer surface ■ Relatively low height and slim shape compared to other nuts ■ Perpendicularity and parallelism of 0.002mm ■ No burrs generated on the screw surface *For more details, please refer to the catalog or feel free to contact us.

Applications/Examples of results
- Due to its relatively low height compared to other nuts, it is suitable for places where the use of other nuts is difficult due to space constraints. - To maintain high precision requirements even during high-speed rotation, all surfaces including the thread face, end face, back face, and outer surface have been precision ground. - In particular, the thread face and end face are ground simultaneously, resulting in a high-precision nut with controlled perpendicularity.
