森本精密シャフト List of Products and Services

A "gauge" is a measuring instrument used to inspect whether the dimensions being processed are within the allowable tolerance range. The usage is very simple; by passing the gauge through both the go side and the no-go side, it is possible to determine high-precision dimensions. We offer "limit gauges for screws" and "plug gauges." 【Features】 ■ High quality at about one-third the price of domestic products ■ Cost reduction is possible as a "working gauge" for on-site inspections ■ Adopted by major companies *For more details, please refer to the PDF document or feel free to contact us.
