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

A lock 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 accommodate the special spring (friction ring), which is then wrapped around the protruding part towards the center, securing 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, thanks to the friction ring ■ Generates pre-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.

New mechanism's locking nut 'NEW Lock Nut'

Exhibits loosening and detachment prevention effects in vibrating environments, single-type locking nut NETIS registration number KK-150023-A.

【Product Overview】A single-type locking nut used on screws in areas subject to vibration, providing anti-loosening and anti-falling effects. The combination of a recessed nut and an eccentric washer exhibits a strong anti-loosening effect due to the wedging action, even in vibration environments where double nuts may loosen. Preliminary tightening can be done by hand. Torque management is required only once.

Locking nut, fixed to the base steel material 'Smart Insert Nut'

Aren't you using nuts welded to the base steel material? Secure the lock nut without welding! Solve the problems of nut installation on the base steel material all at once!

Fixed to the base steel material without welding through external screw processing! There is a way to solve the problems of welding nuts all at once! Are you using nuts welded to the base steel material? Are you facing issues when installing nuts by welding them? Problems with nut welding: - Distortion occurs - Variability in quality with each weld - Deformation happens - A single failure at one point ruined the entire steel material - Requires labor for curing And so on. To break this situation, we developed the 'Smart Insert Nut.' It is a spring-loaded anti-loosening nut, improved from the 'Smart Hyper Load Nut,' which is well-known for its effectiveness in preventing loosening due to vibration. 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 ◆◆◆

[Technical Information] On the Principle of Loosening: Advanced Edition

It provides a detailed explanation of "rotational looseness" and "non-rotational looseness" using diagrams!

The loosening of screws can be broadly classified into two types. One is "rotational loosening," which occurs when the male and female threads rotate relative to each other in the direction of loosening, and the other is "non-rotational loosening," which occurs even when they are not rotating relative to each other. Additionally, screws are used in many aspects of our daily lives. However, when screws loosen when we do not want them to, it can not only disrupt our daily lives but also lead to major accidents. It is important that screws do not loosen when we do not want them to, and that they do loosen when we want them to. Therefore, research on screw loosening and methods to prevent it is considered urgent. [Classification of Loosening] ■ Rotational Loosening ■ Non-Rotational Loosening *For more details, please refer to the PDF materials or feel free to contact us.

[Technical Information] How to grasp loosening? Axial repeated load test

We will introduce the testing method and examples of axial repeated load tests in detail using photographs!

In addition to the perpendicular direction of the bolt axis, axial repeated loads can also cause loosening. In the case of axial repeated loads, if the bolt and nut are properly tightened and sufficient initial axial force is applied, it can be understood that even with a large repeated load of 80% of the bolt yield axial force Fy, common hex nuts are unlikely to experience rotational loosening. On the other hand, if the initial axial force significantly decreases due to some factor, hex nuts and hex nuts with spring washers will completely experience rotational loosening at 50% of the bolt yield axial force Fy, and even double nuts will see the initial axial force drop to about half. From the above results, it can be understood that in the case of hard lock nuts, even when the initial axial force is low or decreases due to some factor, they are less likely to experience rotational loosening. *For more details, please refer to the PDF document or feel free to contact us.

[Technical Information] Basic Knowledge of Understanding Looseness: Proper Tightening of Screws

When tightening bolts, it is important to select the appropriate strength class and friction coefficient that match the target bolt axial force!

To perform safe screw fastening, sufficient initial tightening force F is required, and for that, it is necessary to tighten with an appropriate tightening torque T. The characteristics of the fastening methods for screw fasteners can be broadly divided into two categories: elastic region tightening and plastic region tightening. Therefore, when tightening bolts, it is important to select the strength classification (yield stress) and friction coefficient that correspond to the target bolt axial force. Thus, to perform appropriate screw tightening, it can be said that it is essential to have a good understanding of the friction coefficient, which significantly affects the tightening torque and initial tightening force. 【Fastening Methods for Screw Fasteners】 ■ Elastic Region Tightening: Tightening within the range where the bolt does not yield ■ Plastic Region Tightening: Tightening within the range where the bolt yields and reaches the ultimate tightening axial force *For more details, please refer to the PDF document or feel free to contact us.
