Extensions

Sometimes the KM lock nuts are mounted very deep, so that all the keys fall short, for these jobs we have designed the extensions.

Complete wrenches

• Table of measurements of the KM nuts with the extension mounted.
• The dimension L indicates the depth at which you can work.
• The ØKM dimension is the outside diameter of the nut.
