RotaBolt^® guide

This guide provides a background to the science of achieving and maintaining correct and accurate bolt tension to ensure leak-free startups and ongoing bolted joint integrity.

Bolted joint reliability is an established science but the vast majority of bolted joints are tightened in an uncontrolled manner; the bolt tension achieved at the end of the tightening cycle is unmeasured and unknown.

To guarantee that all bolts are installed to the correct design tension requires a different measuring principle - the principle at the heart of RotaBolt technology.

This guide also provides product details on the different types of RotaBolt tension monitoring devices:

• RotaBolt RB1 Touch and RB2 Touch - simple finger and thumb check of tension accuracy
• RotaBolt Vision - indication of correct tension visible from 20 m distance or can be checked on remote or difficult to access locations by camera drone
