The Vision operates on the same internal airgap technology as the original RotaBolt®, but has a specially developed visual indicator which appears as an unbroken yellow line across the head of the bolt.
As soon as any tension is lost across the bolt, the indicator instantly rotates by 90 degrees to show a distinct right angle break in the yellow line.
This is clearly visible up to 25 metres away and is ideally suited for bolted joints in locations where access is restricted and close inspection difficult.
