World leaders in bolted joint technology and tension control.
RotaBolt™ bolt tension indicators
The RotaBolt™ range provides you with either finger-tip, visual or remote measurement of tension throughout the life of the bolted joint.
RotaBolts™ surpass traditional tightening methods such as:
- Hydraulic Tensioners
- Flogging
- Torque Systems
All of which have severe control limitations and can result in unpredictable bolt tension and joint
failure.
RotaBolts™ are setting new safety standards in a
wide variety of sectors where joints are subject
to fatigue, vibration, pressure containment and
structural slippage.
The current range comprises:
- RotaBolt™ 1 for assured operational reliability in standard bolts from M12 to M135, which can be converted to incorporate the unique Rotabolt indicator featuring air gap technology
- RotaBolt™ 2 provides an even greater range of tension control on installation
tightening and in-service checking by
offering two tension settings in a single
sensor
- RotaBolt™ Vision is the world’s first safety bolt to give a clear, visual indication of loss of tension across the bolted joint, visible from up to 25 metres away
