PG (JAPAN PRECISION GAGES measured Fan She English name first letter abbreviation), co of Fan She thread caterpillar products from line gauge and work taper thread gauge, ring gauge, gauge line parallel plug gauge, embolism, line thread gauge work taper thread gauge, / gauge board, ceramic gauge when customers customized special thread gauge, and high toughness, high strength, wear resistance of zirconia ceramic ring gauge, from soup to nuts. As an ISO9001 certified enterprise, the company always adhere to the traceability of trust standards for the world to bring accurate standards.

Japan tefanshe co., LTD. Was first established in February 1961, and was founded in dongliuxiang, daita district, Tokyo. For the development of the cause, in December of the same year, it was officially changed into the company limited liability company and legal representative organization. When the company joined the Japanese precision measuring machine industry association, the company soon changed into a limited liability company, and the registered capital increased 10 million yen.

Since its establishment, as a gauge manufacturer, it has always made contributions to the development of various industries led by the machinery industry with the precision processing technology condensed together. In the highly informationized society that accelerates the expansion, the market demand is increasingly diversified, complicated and precise. With the continuous progress of mechanical, artificial intelligence and other technological innovations, the pursuit of sophisticated standards in any field.

No matter to ensure the accuracy or reliability of the product, there is no lack of "gauge". From millimeter, micron to submicron, people's requirements for accuracy can be said to be increasingly strict.

Thread plug gauge

GP is the all-through representation

IP refers to inspection stop, WP is working stop, NP is ISO standard stop,

Note: general IP for the final sampling use, WP, NP for full inspection. ISO standard does not discriminate between IP and WP, NP is used for metric threads

Thread ring gauge

GR is a through-terminal representation

IR refers to inspection stop, WR to working stop, NR to ISO standard stop,
