The Rotabolt Vision is the world’s first
safety bolt to give a clear, visual indication
of loss of tension across the bolted joint. |
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 ninety 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.
