Locking nut + theft prevention + tamper-proof nut
"SU-NUT" is a safety and security lock nut adopted in outdoor facilities such as mega-solar power plants. Recently, we have received inquiries to protect equipment from theft and natural disasters at important facilities around the world, including mega-solar power plants being built across the country. The "SU-NUT" features a unique design that enhances visual security deterrence while being impossible to remove with commercially available sockets or wrenches; a dedicated socket is required. The management of the dedicated sockets is handled by Fuji Precision Co., Ltd., and we lend them out for free after signing a "memorandum" with our customers. 【Features】 - Protects your valuable assets - Equivalent functionality and quality to U-NUT - Simply replace the nuts you are currently using - Easy to use, requiring only a special socket as a tool For more details, please contact us or download the catalog.

Company information
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.
