Expanded the shape of the friction ring to 270°! A lock nut that complies with JIS standards.
The "GU-NUT" is a locking nut that adopts a large 270° friction ring to meet the loosening prevention performance specified in JIS B1056, utilizing the friction ring of the "U-NUT." We have enhanced the loosening prevention performance, pursuing further safety and peace of mind. It complies with JIS B1056 "Pre-Loading Torque Type Steel Hex Nut." 【Features】 ■ Complies with JIS B1056 "Pre-Loading Torque Type Steel Hex Nut" ■ The shape of the friction ring has been expanded to 270°, improving performance ■ As a high torque type, the loosening prevention function is further enhanced ■ Prevents early detachment even if axial force decreases *For more details, please refer to the PDF document or feel free to contact us.

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.
