Successfully eliminated loosening permanently with safety bolts and nuts! Passed JQA high-speed vibration loosening test!
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 further 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 fastened object in a wedge shape, preventing the washer from rotating and 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 available for download.
Ratchet mechanism, won't loosen due to the biting protrusion. New type of small-diameter cap bolt.
The "W-V-LOCK Yurumanzō New Model" employs a ratchet mechanism between the bolt, nut, and washer, and additionally features protrusions on the bottom surface of the washer that bite into the workpiece, successfully eliminating loosening almost permanently. This product is the new model of "W-V-LOCK Yurumanzō," in the hex socket bolt (small diameter cap bolt) type. 【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. ■ It does not loosen even under strong vibrations or long-term use. ■ If removal of the screw is necessary, it can be removed by applying a slightly higher loosening torque than the tightening torque. *For more details, please refer to the PDF document or feel free to contact us.

With a small force, you can achieve a large torque! Thanks to the function of the bearings, your usual tightening tasks can be done easily.
The "Strong Nut" is a product that allows for high torque with minimal force due to its built-in ball bearings. The force required for tightening is usually less than half that of a standard nut. Since the bottom surface of the nut does not move, washers and clamps are not damaged. We also offer the "Strong Washer," which is used set between the nut and the clamp, and the "Strong Ratchet Torque Wrench," which is suitable for torque management of the Strong Nut. 【Features】 ■ Built-in ball bearings ■ The force required for tightening is usually less than half that of a standard nut ■ The bottom surface of the nut does not move, preventing damage to washers and clamps ■ Bearings absorb vibrations, preventing loosening *For more details, please refer to the PDF document or feel free to contact us.
