Swiss Quality Lock Nuts For 40 Years

In all these years, we have held on to Switzerland as a production location and we are proud to still be able to supply customers all over the world with Swiss-quality products from Biel.

We now also manufacture adjusting nuts according to your requirements. Thanks to our modern machinery, we can implement special designs quickly and cost-effectively.


The lock nuts are manufactured in a wide variety of designs. Our lock nuts are available with radial or axial clamping, in excess width, or stainless steel.

 

The lock nuts are made of high-quality steel and are subject to the highest standards of accuracy. This ensures that the load is evenly distributed over the threads and the clamped elements. This leads to higher rigidity and longer service life of the units.

 

To facilitate the assembly of the lock nuts and to prevent damage, we recommend our extensive range of accessories. Socket spanners and torque adapters can be used to define the forces acting on the units.
