Test video of the anti-loosening bolt and nut 'W-V-LOCK' now available.
Successfully eliminated loosening permanently with our safety bolts and nuts! Cleared JQA high-speed vibration loosening test! Samples will be distributed at the Mechanical Element Technology Exhibition!
The "Yurumanzo (W-V-LOCK)" is a safety bolt and nut that successfully eliminates loosening permanently by adopting 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 tightened object in a wedge shape, preventing the washer from rotating and providing a loosening prevention effect for the entire screw. ■ No loosening occurs even under strong vibrations or long-term use. ■ A high safety and durability loosening prevention mechanism for screws. ■ Patent obtained. * For more details, please request documentation or view the PDF data available for download.
