Industrial non-loosening screws and nuts, sample support available!
Successfully eliminated loosening permanently with safety bolts and nuts! Passed JQA high-speed vibration loosening test! Released case photos used in industrial applications!
The "Yurumanzo (W-V-LOCK)" is a safety bolt and nut that successfully eliminates loosening permanently by employing a ratchet mechanism between the bolt, nut, and washer, and by incorporating protrusions on the bottom surface of the washer that bite into the workpiece. All five units tested in the vibration loosening comparison test conducted by the Japan Quality Assurance Organization passed without loosening for over 17 minutes. 【Features】 ■ The bolt and washer are connected using a ratchet system, with several protrusions on one side of the seating surface. ■ The protrusions bite into the clamped object in a wedge shape, preventing the washer from rotating, thereby providing a loosening prevention effect for the entire screw. ■ Does not loosen even under strong vibrations or long-term use. ■ A loosening prevention mechanism with high safety and durability. ■ Patent obtained. *For more details, please request materials or view the PDF data from the download. *If you would like a sample, please contact us.
