Discover more about RotaBolt, the technology used and its applications worldwide
What is RotaBolt?
When a standard bolt is tightened, the tension achieved is completely unknown, RotaBolt load indicating fasteners are measuring devices and highly accurate indicators of clamping force or tension.
How does it work?
Achieving and maintaining the correct clamping force, or bolt tension, is essential in assuring bolted joint integrity. 85% – 90% of all bolted joint failures are caused by insufficient bolt tension.
Why does it work?
Over 90% of all bolted joint failures can be attributed to low bolt tension on installation tightening. Achieving and maintaining the correct installed design tension will eliminate failures.
Where does it work?
RotaBolt load indicating fasteners are in use around the world to provide leak free joint integrity or assure structural stability in applications subject to vibration, pressure or thermal cycling.
Rotabolt Product guide
RotaBolt load indicating fasteners are bolts and studs that allow a specific tension to be applied
A bolt is converted with a RotaBolt indicator and cap. As the load indicator fastener is stretched, the cap locks at the specified tension value.
Using the same air-gap technology, Vision has a specially developed indicator which appears as an yellow line across the head of the fastener.
The RotaBolt-TD system is the first system give genuine remote and wireless monitoring of bolted joints from anywhere in the world.
BreakBolt is a tension monitoring bolt that is deliberately designed to fail at a predetermined tension level, It also incorporates RotaBolt technology.
