The opposing angle of the hook is managed according to internal standards.
The material used is "spring stainless steel wire - SUS304-WPB." This spring requires the hooks at both ends to be fixed with screws during assembly, making the opposing angle of the hooks important. Therefore, we manage the opposing angle of the hooks with a rather strict tolerance of "±5 degrees." According to JIS standards, the allowable tolerance for the opposing angle of the hooks is defined as "by agreement between the parties." In fact, it does not explicitly specify "plus or minus how many degrees." Our company has established internal standards separate from JIS standards to manage the opposing angle of the hooks. Additionally, if customers have stricter requests, we respond as much as possible by creating limit samples and other means. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully. Technical Contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com Tsuruga Spring Co., Ltd. for springs We also support web meetings.
