Gauge for parallel threads
The limit method is a general method for judging the acceptance of parallel threads using a screw gauge.
In order to judge the pass/fail of product screws, we inspect with a go-side gauge and a go-side gauge to guarantee accuracy.
Gauges for metric threads are divided into the following two types. There are the current JIS ISO grade gauge system (6g) and the old JIS grade 1, 2, and 3 gauge system, so please specify when ordering.
