Basic Knowledge of Screw Products: What are the differences between the old JIS and new JIS for flat washers?

Basic Knowledge of Screw Products: What are the differences between the old JIS and new JIS for flat washers?

The names have been divided into old and new because the dimensions have changed slightly over the years!

Originally, flat washers were created based on the international standard ISO 7089 to establish JIS B 1256. Although it remains JIS B 1256, the dimensions have gradually changed over the years, leading to the distinction between old and new versions. 【JIS B 1256: 1963】The so-called old JIS. If it is marked as "P=〇" in the SEMS, this refers to the dimensions of this flat washer. 【JIS B 1256: 1978】The so-called new JIS. Generally, it is often referred to as "ISO." In SEMS, it is marked as "I=〇." 【Old JIS B 1256: 1998, JIS B 1256: 2008】These versions are currently not circulating in the market. *For more details, please refer to the related links.
