GO and NO GO snap gauges are specified for a shaft 36.000 mm with deviations +0.070/+0.010 mm. Gauge tolerance is 5% of the stated “hole tolerance”. Under the source’s ISO gauge-design convention, select the printed respective GO/NO GO sizes.
Work tolerance = 36.070−36.010 = 0.060 mm; 5% gauge allowance = 0.003 mm. Inward-offset limiting sizes are 36.010+0.003 = 36.013 and 36.070−0.003 = 36.067 mm, the official **A**. The source is inconsistent in calling this a shaft/snap gauge but referring to hole tolerance and ordering GO at the lower limit. For a shaft, the GO snap opening checks the largest permitted shaft and NO GO the smallest. Official option grading is retained, with that order qualification explicit.
