Screw Thread Gauge Common Sense.
The common metric thread gauges including ring gauges and plug gauges are used to
calibrate thread workpieces by GB and ISO standards.It conforms to ISO1502 and GB/T
3934 standards.
Thread gauges according to the using performance points:
1)Working gauge: Manufacturing and inspection workpiece thread use the thread gauge.
2)Acceptance gauge: Inspection department or the user representatives inspect workpiece thread use the thread gauge.
3)Checking gauge:Manufacturing and inspection working gauge use the thread gauge.
