Thread plug gages (ελεγκτήρες σπειρωμάτων) are precision tools used to verify the accuracy of internal threads in a hole. They ensure that the internal threads are correctly sized and conform to specified tolerances, allowing proper assembly with external threaded components.
Ring gages (δαχτυλίδια ελέγχου σπειρωμάτων) are used to inspect the external threads on bolts, shafts, or other cylindrical objects. These gages ensure that the external threads meet required specifications, guaranteeing that the parts will fit and function correctly in their intended applications.
