The test was conducted for 17 minutes with 30,000 vibrations! The patented dome-shaped washer passed!
We will introduce the differences between the washer patent and JIS standards. The test was conducted for 17 minutes with 30,000 vibrations. The results of the vibration test showed that the commercially available spring washer fell off in 2 minutes and 13 seconds, while the double nut using two commercially available nuts fell off in 7 minutes and 50 seconds. However, our "patented dome-shaped washer" passed the 17-minute, 30,000 vibration test. [Vibration Test Results] ■ Commercially available spring washer: 2 minutes and 13 seconds - fell off ■ Double nut using two commercially available nuts: 7 minutes and 50 seconds - fell off ■ Patented dome-shaped washer: Passed 17 minutes and 30,000 vibrations *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company aims to create original products that communicate with the world using creativity and bring about a new breeze. We are also challenging ourselves in research and development of metal processing, which is essential for fastening points in automobiles, aircraft, and industrial machinery products. While parts made to JIS standards are easy to manufacture, there is no guarantee of winning in price competition. However, there is no such concern for patented parts; they may hold value in licensing agreements. Wouldn't it be possible to become a monopoly manufacturer (for production and sales) with these patented parts? Shall we work towards making this part recognized as the standard when people think of washers?
