1. Fastener – a threaded device that clamps two or more parts together.
2. Torque – turning a previously tightened fastener another few degrees to evaluate the clamping
force holding the joint together. The target is a clamp load that can be sustained when the
assembly parts are subjected to service load.
3. Qualifying a joint – determining the amount of tension attained at a given torque value and
relating the tension to the angular displacement of the bolt.
4. Audit – an evaluation of the manufacturing process to determine whether a part or group of
parts meets the required specifications.
5. Route – The complete set of inspection plans which "Sets Up" the data collector for use on an
application. The Route is a set of Setups usually to be collected by one person in one shift.
6. M-alpha – auditing method – presents the tightening torque as a function of the bolt assembly
angle, which correlates the stretch of the bolt to the angular displacement of the fastener. This
relationship provides a method of monitoring the tension in the joint, or bolt stretch, by
analyzing the torque-angle signature of the audit.
7. Alias – tool configuration used by the collector to define its port functionality.
