The majority of installations are exposed to external forces such as vibration and variable dynamic loads. Weather conditions, such as wind and temperature changes, can also affect a bolted connection.
If some of the parts within a bolted connection are allowed to move, it can eventually become loose.
The "No Need For Retightening" certification course aims to ensure the installation of a safe and secure bolted connection. In order to be certified you must go through all modules and pass the final test.
The course is built up of the following modules:
- The Nord-Lock washer
- Bolt theory
