A bolt’s function essentially boils down to applying a high enough Hose Clamps force that when external forces are applied, transverse movement and separation cannot occur. Using calibrated torque tools to tighten fasteners and apply that clamp force is far superior to going by the user’s judgement or feeling. Or, as one senior technician calls it “The One Grunt or Two Grunts Method”. Measuring torque alone, however, does not ensure a proper installation.

1. Torque is an indirect indicator of Tension.

Torque is the measurement of twisting force needed to thread the fasteners together.

2. Tension is the force that actually holds an assembly together. Put another way:

A bolt can stretch similar to a spring, as it becomes tightened once all the parts of the assembly are brought together.

The higher the torque applied to the fastener, the more tension is created as the bolt stretches.
