Rotabolt Vision – with visual indicator
Rotabolt Vision is the world’s first safety bolt that clearly visualises a load tension reduction in a bolted joint. Rotabolt Vision is based on the same design as the original but the capsule has been modified and equipped with an internal spring construction, with clear marking on the outside that gives a visual indication of load tension reduction.
When the load tension falls below the desired minimum value, the capsule rotates 90 degrees and, rather than a line, a cross is visible. This cross is fully visible from up to 25 metres.
Rotabolt Vision is perfect for applications that are difficult to reach for inspection or in situations where nearby staff can see that a problem has arisen.
