Product Overview

JIS Standard Spring_Image

We standardized the springs by adopting cross section materials for the first time in Japan. Tohatsu JIS standard was created using those skills. It can gain higher loads in smaller spaces than round coil springs.

The standards established as criteria for Tohatsu JIS Standard Springs are the Japanese Industrial Standard JIS B 5012:2008 (Coiled helical spring for press dies), Japan Metal Stamping Association standards, and Japan Die & Mold Industry Association standard.
