Tensioners & Torque Systems
SEE AD ON PAGE 59
The proper alignment of a bolted joint can be achieved by using either torque or tension meth-ods of bolting. Proper bolt loads must be realized during installation or the integrity of the joint will be compromised, leading to misalignment and, if left unchecked, the ultimate failure of the joint. In this issue, we look at some of the tensioners and torque systems available today.
