Hi raymo,

It may relate to a safety and/or critical significant characteristic on the fastener, especially if used in automotive or aerospace applications and usually is indicated on drawings to highlight special attention in process control during manufacturing or in service. For example - a fastening or test torque for a safety critical seat belt fastener or critical dimension.

Best
