basic information

<Installation Procedure> 1. Pass the bolt through the fastening component. Ensure that the bolt has a thread accuracy of 6g (Grade 2) and that the tip of the threaded section has been chamfered. 2. Manually screw in the bolt until the friction ring makes contact with the tip of the threaded section. *Note: It is not possible to screw in from the side of the friction ring. 3. Tighten using a wrench or other fastening tool. 4. Confirm that the threaded section of the bolt extends more than two pitches from the friction ring. When removing, use a wrench or similar tool to unscrew until the friction ring is free from the bolt's threads. Once the friction ring is no longer in contact with the bolt's threads, you can unscrew it by hand. *For more details, please refer to the PDF document or feel free to contact us.

Since our establishment in 1962, Fuji Precision has focused exclusively on the research and development of locking nuts, growing into a comprehensive manufacturer of locking nuts. The 'U-Nut' brand was the first in the industry to introduce the "metal ring locking function" to bolts and nuts, which were traditionally considered prone to loosening. This groundbreaking product received a significant response upon its release and has now grown to capture a 50% share of the domestic market, becoming synonymous with locking nuts. Although bolts and nuts may be considered small parts, they play a crucial role in connecting functions and technologies. They can be described as cross-point technology that combines cutting-edge technologies and opens up new technological fields. Fuji Precision regards this theme as an eternal proposition and has been committed to product development that anticipates the needs of the times, while pursuing high quality and high added value in our products. Our future goal is to become the world's number one comprehensive manufacturer of locking nuts. We will continue to strive to create products that meet your trust and contribute to the industrial sector and society.
