Since our establishment in 1962, Fuji Precision has focused solely 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 to loosen. 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. Though small parts, bolts and nuts play a crucial role in connecting functions and technologies. They can be seen as a cross-point technology that combines cutting-edge technologies and opens up new technological fields. Fuji Precision has taken this theme as an eternal proposition, working on product development that anticipates the needs of the times while pursuing high quality and added value in our products. Our goal for the future is to become the world's number one comprehensive manufacturer of locking nuts. We will continue to strive for product development that meets your trust and contributes to the industrial sector and society through even greater efforts.
