The science of bolted joint reliability is dependent upon three factors - joint design, bolt quality and design tension on installation. |
We deliver technology driven assurance that guarantees installation to a pre-set tension and continues to accurately measure the maintained tension across the bolted joint.

Standard bolts are converted by inserting the Rotabolt indicator which incorporates an integral gauge pin and grease filled control cap.
|
|
The unique Rotabolt design incorporates internal air gap technology and 100% load test calibration. The consistency of the design criteria guarantees an indicator accuracy of +/- 5% throughout the life of the bolt .
|
|
Before installation the Rotacap spins freely. As the bolt is tightened, it stretches elastically and the Rotacap locks at the bolt's specified, load test calibrated tension value
|
|
As soon as any tension is lost across the bolted joint, the Rotacap immediately rotates freely to give a clear indication of tension loss.
