Torque Auditing Examples

The Theory behind static auditing is this: If 90 Nm of torque was initially applied to reach a specific tightness or tension, reapplying 90+ Nm of torque will overcome the residual friction and cause the fastener to move.

In other words the audit will find the fastener breaking away at 90 Nm.

The Reality of static auditing is this: To cause a previously tightened fastener to move, the residual friction must be overcome.

Since static friction is usually greater than dynamic friction, the breakaway point is usually greater than the installation torque.

This fastener's breakaway point could be in the 90s or in the 100+ Nm range.
