What is the value of hardness for plug and ring gauges used for self-holding tapers?

(a) 750 to 860 HV

(b) 120 to 540 HV

(c) 550 to 740 HV

(d) 900 to 1200 HV

This question was addressed to me in final exam.

This key question is from Gauges for Tapers topic in division Limits, Fits and Gauges of Engineering Metrology

Best answer
The correct option is (a) 750 to 860 HV

For explanation I would say: Good quality steel is used for making these gauges and these are suitably heat treated to give hardness of 750 to 860 HV and for stabilization. Gauges surfaces should be free from rust, crack and burrs.
