Areas of Application
- Generating a bolt pre-tensioning force for which 100% operational sequencing, safety and data logging are required.
- Engine-building: Main bearing, connecting rod bearing, cylinder head
- Power plants: e.g. Turbines, compressors
- Ring gear bolt connections: e.g. wind power plants
- Tower fittings: e.g. crane construction
- General mechanical engineering

Quality Assurance
All MMDS are checked for 100 % process security. During order handling, they are accompanied by ongoing quality assurance measures and supplied with extensive documentation.
