Product Description
Ring tooth gauge, gauge, thread plug gauge, thread ring gauge
Differences between JIS and ISO standards for thread ring teeth
- For ISO grade measurement methods, there is no difference between pass and stop for inspection and processing.
- To judge whether the stop gauge is qualified or not, when the ISO grade measurement method is used, the screwing must not exceed 2 turns; when using the 1, 2, 3 grade measurement method, the screwing must not exceed 2 turns.
- When the ISO grade measurement method is adopted, the inspection of the thread ring gauge is matched with the gauge, which is a through-stop limit type.
Standard thread gauge
The standard thread gauge consists of a set of thread ring gauges and thread plug gauges that are precisely matched with each other. Different from the limit gauge, the basic shape of the thread is correctly manufactured, so as long as the thread ring gauge and thread plug gauge can pass the product thread, it can be judged as qualified. Since it is impossible to determine the degree of fit between products, when precise fit between products is required, use a limit-type thread gauge.
Precautions when using ring tooth gauge
- When using a standard thread gauge, the thread plug gauge can also check the function of the mating gauge.
- When using threaded ring gauges that are not interchangeable with threaded plug gauges, even if the respective gauges are judged to be qualified, the interchangeability between products may not be guaranteed.
- If the customer already has a standard thread plug gauge, when re-making the standard thread ring gauge,Be sure to pay attention.
