We also handle overseas standard fastening components such as DIN, ANSI, and Witt, which are difficult to procure domestically in Japan.
In addition to the widely used metric screws (JIS standard M screws) in Japan, there are various standards around the world, such as inch screws (Unified and Whitworth) and DIN (German Industrial Standards), which are used in diverse industries and products. Since these standards have developed separately and are not compatible with each other, paying attention to the standards is an important point for ensuring the safety and reliability of products.

Company information
Tobimoto Sangyo Co., Ltd. was established as a specialized trading company for screws and fastening parts in Tanimachi, Osaka City, shortly after World War II, where many shops dealing in machinery and tools lined the streets. Today, we have built over 75 years of history in the Osaka Machinery Wholesale District (commonly known as the Machinery District) located in Higashi-Osaka City, a town of small and medium-sized enterprises. Screws and fastening parts are used in various industries as the unsung heroes behind the scenes. They may not be very noticeable, but they are essential products without which assembly cannot take place. We take great joy and pride in having specialized in these screws and fastening parts for many years. Our ability to continue our business activities over the years is thanks to our customers and all the stakeholders who support us.
