The "Washer-attached U-NUT" is a locking nut that accommodates loose holes and blind holes due to its large washer diameter. In response to requests from various sources, we have integrated a large washer into the hexagonal shape of the U-NUT. Since the nut, spring washer, and washer are all integrated, it reduces labor, improves work efficiency, and minimizes the risk of forgetting to install parts as well as the hassle of inventory management. 【Features】 〇 Galvanized (SS400) ○ Stainless steel (SUS304) ○ No need for spring washers or flat washers ○ Usable with anchor bolts ○ Thread pitch is standard For more details, please contact us or download the catalog.

The "CLIP U-NUT" is a specialized U-NUT designed to facilitate work in locations that are difficult to access or unreachable, such as the installation of soundproof walls on highways. By simply drilling a hole in the component, there is no need for nut welding or screw tapping. Additionally, the guide ring function makes positioning easy. The one-sided fastening method reduces the number of workers required and achieves a total cost reduction. 【Features】 ■ The clip fittings are compatible with the function of square washers. ■ Contributes to the simplification of work. ■ Reduces the number of parts. ■ Shortens construction time. *For more details, please refer to the PDF document or feel free to contact us.

"BLU-NUT" is a research and development product that incorporates the functionality of a U-NUT into a blind nut. Based on feedback from everyone, we have integrated Fujiseimitsu Co., Ltd.'s U-NUT technology into the blind nut. We believe that this "BLU-NUT" will lead to further improvements in our customers' work efficiency and cost management. 【Features】 - Reduces the time and effort required for complicated pre-process tasks - Simple operation that can be tightened with a riveter or nut driver - Contributes to total cost reduction - Reduces the number of parts, making management easier - Equipped with measures to prevent nut rotation and bolt seizure For more details, please contact us or download the catalog.

The "Cap U-Nut" is a locking nut that covers the tip of the bolt with a cap, enhancing its appearance. It improves safety during contact with the bolt and protects the contacted objects, addressing PL law measures. 【Features】 ■ Covers the tip of the bolt with a cap ■ Enhances appearance ■ Improves safety during contact with the bolt ■ Protects contacted objects ■ Addresses PL law measures *For more details, please refer to the PDF document or feel free to contact us.
