We have acquired and maintained ISO9001 certification, but do we need to use ISO-standard thread gauges for the thread gauges we use in the future?
It is not necessary to use ISO standard thread gauges for ISO9001. ISO9001 is a standard for quality assurance systems. The thread gauges used must match the grade indicated on the product drawing.
However, in recent years, there has been a rapid shift to ISO standard thread gauges, so it is necessary to pay attention to world trends in order to avoid problems. If you are considering switching, please contact us.
