| murff Joined: 27 Oct 2009 Posts: 620 | Posted: Wed Jan 03, 2024 8:10 pm Limit snap gauges are used to check external dimensions, for example on a shaft. They are used in series production and they indicate when an actual dimension is within a tolerance of the nominal dimension. The limit plug gauge has two sides - the reject side (AUS) and the good side (GUT)... There is a defined scale of values - k 6 says 12.001 and 12.012mm is this case (it is difficult to explain this in English...) Both companies, Herzstark Wien and Contina AG Mauren, manufactured measuring gauges | ||
