Hemco GO 18.7500MM NO GO 18.8700MM Plug Gauge

This Hemco GO 18.7500 mm NO GO 18.8700 mm plug gauge is a fixed-dimension bore inspection tool used to verify cylindrical hole sizes in quality control and machining environments. It features a GO end sized at 18.7500 mm and a NO GO end sized at 18.8700 mm, providing a straightforward pass/fail check for bore dimensions. In routine inspection, technicians compare a workpiece bore against the two ends to confirm the diameter falls within the intended range without requiring a full calibration run. This type of gauge supports quick, repeatable checks in shop floors, tool rooms, and manufacturing lines where consistent hole sizing is critical, helping ensure components fit properly in assemblies and meet dimensional specifications.
