Go No-Go Plug Gage 6mm Gauge Dia Gcr15 Bearings Steel 0.001mm Precision
Specification:Gauge Diameter: 6mmPrecision: 0.001mmMaterial: Gcr15 Bearing SteelLength: 50mm / 1.97 InchFeature:Made of bearing steel, with high hardness, strong wear resistance, and heat treatment processing for durability.0.001mm precision, accurate measurement. Roughness is less than 0.2UM, smooth surface without burrs.Used to measure the size or depth of holes, check the distance between two holes, and can also be used as a go-no-go gauge. Widely used in high-precision technical such as electronic boards, circuit boards, and precision machinery manufacturing. An essential tool for the standardization of detection holes.To keep the measurement accuracy, please do not scratch the surface, and do anti-rust treatment after use.
