Ceramic, Step Limit Plug Gauge H7

A plug gauge with Go and No-Go in one area, eliminating the need to change the direction of the gauge and improving efficiency.
[Features]
· A pair of gauges with external dimensions based on the maximum and minimum allowable dimensions as references.
· Can be used for obtaining fit compatibility between the hole and the shaft.
· Material with exceptional wear resistance in comparison with steel, which strongly resists changes over time.
· No concerns about rust or corrosion on the measurement surface, with extremely simple maintenance and management after use.
· Material with a thermal expansion coefficient almost identical to steel. Measurement surface is nonmagnetic material that will not become magnetized.
· There is little change in plasticity due to scratches or dents and there are no burrs or bulges.
[Applications]
· Used for hole diameter inspections.
