Locking nut "V Nut" [Can be used directly on the bolt in use]

Locking nut "V Nut" [Can be used directly on the bolt in use]

A locking nut that can be used directly on the bolt in use! Usable even after being removed multiple times!

The locking nut "V Nut" consists of two components: the nut itself and a special spring. A groove is machined into the top surface of the nut to fit the special spring (friction ring), and the protruding part is wound inward toward the center, fixing the friction ring to the top of the nut. 【Features】 ■ Can be used directly with currently used bolts ■ Does not fall off even when the bolt and nut are in an intermediate position due to the action of the friction ring ■ Generates pre-tension torque after removal, suppressing "rotational loosening" ■ Higher safety and workability compared to standard nuts ■ Excellent heat and cold resistance, with no concerns about functional degradation *For more details, please request documentation or view the PDF data available for download.

Fixed to the base steel material without welding through external screw processing! There is a way to completely solve the problems of welding nuts! Are you using nuts welded to the base steel material? Are you facing issues when attaching nuts through welding? Problems with nut welding: - Distortion occurs - Variability in quality with each weld - Deformation happens - A single failure at one point ruins the entire steel material - Requires time-consuming protection measures And more. To break this situation, we developed the 'Smart Insert Nut.' This is a spring-integrated anti-loosening nut, improved from the 'Smart Hyper Load Nut,' which is well-known for its effectiveness in preventing loosening due to vibrations. By processing external threads on the outside of the nut, it can now be fixed to the base steel material simply by tapping, eliminating the need for welding. Not only does it solve the welding problem, but it also addresses the issue of nut loosening!! ■ No welding required! ■ No rust prevention treatment needed! ■ Improved work efficiency! ■ No worries about thermal deformation! ■ Ensured accuracy of nut positioning! ■ No concerns about bolt loosening! ◆◆◆ We will send you a free sample set ◆◆◆
