Limits and fits (IS system): interpretation of ‘‘100 H6/g5’’ Under Indian/ISO limits and fits notation, what does ‘‘100 H6/g5’’ indicate about the size reference? Choose the correct interpretation.

Difficulty: Easy

Actual size is 100 mm
Basic size is 100 mm
Difference between actual and basic size is 100 mm
None of the above

Correct Answer: Basic size is 100 mm

Explanation:

ConceptIn the notation 100 H6/g5, the number (100) denotes the basic size in mm. The letters and numbers (H6 for hole, g5 for shaft) specify fundamental deviations and tolerance grades with respect to that basic size.

Final AnswerBasic size is 100 mm
