Generally speaking, there is no limit. The MIN is M0.7 mm and Max M90 mm.

Yes. The obvious advantage of the  ESLO lock nut is that it is especially suitable for soft materials because its load is evenly distributed.
By evenly distributing the load, interlocking with the entire bolt, and re-distributing the compressive force in the radial direction, the bolt can effe......

Generally speaking, we do not recommend this approach. However, depending on the specific situation, it can also be formed by cold extrusion to form a 30 degree wedge thread, Or re-drill the hole and tap the thread with a larger anti-loosening tap.

We recommend using a drill bit larger than the standard thread size to drill the bottom hole. Although this work is not an absolute requirement, it will extend the life of your tools. For specific dimensions, please contact the relevant engineers.

Inspect bolts according to 6g or 6h standard. If the thread meets the 6g or 6h class standard, it should be able to match with ESLO thread.

Definitely not.
