HLN (Hard Lock Nut) / HLB (Hard Lock Bearing Nut)
The Hard Lock® nut, born in Japan and growing globally, possesses a strong anti-loosening effect not found in other lock nuts, along with excellent workability and ease of attachment and detachment. Could the principle of a wedge be applied to prevent loosening? This theme was tackled, and after repeated trial and error, the Hard Lock nut was completed.
![[Technical Information] On the Principle of Loosening: Advanced Edition](https://image.mono.ipros.com/public/product/image/9a0/2000560038/IPROS96184672065473900573.jpeg?w=280&h=280)
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. There is "rotational loosening," which occurs when the male and female threads rotate relative to each other in the direction of loosening, and "non-rotational loosening," which occurs even when they are not rotating relative to each other. Furthermore, screws are used extensively in our daily lives. However, when screws loosen when we do not want them to, it can not only disrupt our 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. Research on screw loosening and prevention is considered urgent. 【Classification of Loosening】 ■ Rotational Loosening ■ Non-Rotational Loosening *For more details, please refer to the PDF document or feel free to contact us.
![[Technical Information] How to detect looseness? Axial repeated load testing.](https://image.mono.ipros.com/public/product/image/196/2000560040/IPROS02079253595203390592.png?w=280&h=280)
We will introduce the testing method and test examples of axial repeated load testing in detail using photographs!
In addition to the direction perpendicular to 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, even when subjected to a large repeated load of 80% of the bolt yield axial force Fy, it can be understood that even standard hex nuts are less likely 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.

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 tightening methods for screw fasteners can be broadly divided into two categories: elastic region tightening and plastic region tightening. Therefore, when fastening bolts, it is important to select the appropriate strength classification (yield stress) and friction coefficient that correspond to the target bolt axial force. Thus, to perform proper screw tightening, it can be said that it is essential to have a good understanding of the friction coefficient, which greatly influences the tightening torque and initial tightening force. [Tightening 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 limit tightening axial force *For more details, please refer to the PDF document or feel free to contact us.

We will provide detailed information about commonly used metric threads for fastening, including diagrams and tables.
In the fastening of mechanical structures (screw fasteners), screws are important components. They can be removed when necessary. The ability to repair mechanical structures and reuse them is a key feature. According to the screw fastening general rules (JIS B 1083:2008), screw fastening is defined as the method or state of joining two or more items by fitting the threaded part of a bolt with the nut or the internally threaded part formed in the item, and tightening the screw. A screw fastening assembly is defined as the entire structure with a screw fastening part or a part of the structure that includes the screw fastening part. Our technical information site "Screw Fastening Technology Navigation," which contributes to solving screw fastening challenges, provides detailed information about "the structure of screws." Please take a look through the related links. *For more details, please feel free to contact us.

I will introduce tensile stress σ and shear stress τ!
When tightening bolts and nuts, the points to be aware of regarding the relationship between the tightening torque and axial force in the threaded joint can be broadly categorized into the following two points: (1) When the tightening torque is too high relative to the strength of the bolt and nut. (2) When the tightening torque is too low relative to the strength of the bolt and nut. Our technical information site "Screw Fastening Technology Navi," which contributes to solving issues related to screw fastening, confirms the stresses that occur inside the bolt during fastening and addresses the issue of screw failure when the tightening torque is too high, providing detailed information on this topic.

We will provide a detailed introduction to general corrosion, pitting corrosion, and galvanic corrosion!
The main forms of corrosion include "uniform corrosion, pitting corrosion, and galvanic corrosion." Other types of corrosion include "crevice corrosion," which occurs due to the formation of an oxygen concentration cell in tiny gaps on the order of microns, "grain boundary corrosion," where the grain boundaries preferentially corrode, "erosion corrosion," which involves the action of wear by fluids, and "high-temperature oxidation," which occurs in high-temperature atmospheres or steam. Our technical information site "Screw Fastening Technology Navi," which contributes to solving issues related to screw fastening, features the three main forms of corrosion (uniform corrosion, pitting corrosion, and galvanic corrosion). Please take a look through the related links.

Bearing locking nut
Precision lock nuts are nuts used for securing bearings, and they can fully demonstrate their effectiveness in rotating bodies that require high precision. Rotating bodies are becoming smaller and faster, and there is a demand for high precision with minimal runout. In such cases, using high-precision lock nuts makes this possible and significantly reduces assembly time for equipment. Our precision lock nuts are manufactured to achieve runout precision of less than 3μm by simultaneously grinding the threaded part and its end face. Therefore, when the bearing end face is secured with the lock nut, it is possible to assemble with minimal eccentricity in the shaft part and achieve high precision. Additionally, the effective diameter of the threads is managed and manufactured towards the lower limit, which minimizes play with the shaft part when tightened, making it less likely to loosen due to vibrations. Furthermore, assembly and disassembly can be easily performed, making it very convenient for regular inspections, maintenance, and repairs of machinery.
