Supplement | In the ISO grade gauge, the distinction between use for inspection and use for manufacturing has been eliminated for both the go and no-go sides. The pass-fail decision for the no-go gauge is based on the ISO grade gauge method on screws not being turned in excess of 2 rotations. In the conventional JIS gauge (1, 2, 3 grades) method, the screws are not turned in excess of 2 rotations. |
