Liability

Many events in the operating environment may affect the tightening process and shall require a validation of results. In compliance with applicable standards and/or regulations, we hereby require you to check the installed torque and rotational direction after any event that can influence the tightening result. Examples of such events include but are not limited to:

initial installation of the tooling system
change of part batch, bolt, screw batch, tool, software, configuration or environment
change of air- or electrical connections
change in line ergonomics, process, quality procedures or practices
changing of operator
any other change that influences the result of the tightening process

The check should:

Ensure that the joint conditions have not changed due to events of influence.
Be done after initial installation, maintenance or repair of the equipment.
Occur at least once per shift or at another suitable frequency.
