Limit Screw Ring Gauges, ISO Method JISB0251/0252

[Features]
· Uses the limit system, the most common method for parallel screw gauges, in which the accuracy is guaranteed by managing the limit of the product screws for through/blind.
· There are two basic limit types: the ISO classification gauge type and the conventional JIS classification gauge type.
· The conventional JIS gauge system distinguished inspection and machining on the gauge no-go side, but the ISO gauge system is simplified, removing this distinction.
· Scissors-type gauge for exterior use is the same.
