No Need For Retightening

Course information

Target group:

Installers and maintenance personnel (i.e. oil and gas, windmill, railroad and energy industry etc.)


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:

- Introduction
- The Nord-Lock washer
- Assembly
- Tightening
- Bolt theory
- End
