GAUGE CATALOGUE

Since its founding in 1925, KURODA Precision Industries Ltd. has continued to advance with the history of gauges in our country, and has been striving for improvement in the product quality and reliability. As a result, KURODA has successfully received the highest class evaluation as a pioneer of gauge manufacturer, such as an authority to indicate JIS "Grade 1" thread gauge mark for the first time in Japan and a production license for API gauges first time ever in the East. The importance of gauges has been recognized anew, because they play a significant role in quality control and quality...

Limit Gauges for Threads This gauge is used to control the dimensional accuracy of threads and to assure the compatibility of threads. This gauge is used to inspect a threaded part by means of two threads (GO and NOT GO having dimensional differences) at the high limit and low limit of the predetermined dimensional accuracy of such threaded part. Therefore, it is called a limit gauge for threads. i£sEi§—#)fet/JH Types and symbols—For internal threads Gauges for traditional JIS gauge system Applies to those for metric threads grade 1 to grade 3, straight pipe threads PF and unified screw (GO thread...

WWtZblT—V Standard Usage note •When large diameter thread products are to be inspected or production quantity is small, standard thread gauges are cost-effective. However, they are not equal to limit gauges for threads from a quality control •Standard thread gauges are equivalent to (not the same as) the GO thread gauges of limit gauges for threads prescribed by JIS, and they are not provided with the function of NOT GO thread gauges. Therefore, if the fit of a product to the standard thread gauge is loose, it is necessary to measure the pitch diameter of the product, when •As the friction of...
