![Anti-loosening nut "Muscle Nut" [Does not loosen regardless of time!]](https://image.www.ipros.com/public/product/image/5b3/2000105208/IPROS30354648485620334097.jpeg?w=280&h=280)
Anti-loosening nut "Muscle Nut" [Does not loosen regardless of time!]
A drop prevention nut that does not loosen and is unaffected by time! It has a safe structure that prevents dropping even if you forget to tighten it or if it is loosely tightened!
The "Muscle Nut," a drop prevention nut, features a safety structure that prevents it from falling off even if forgotten to be tightened or if it is loosely tightened. It has achieved complete drop prevention that does not loosen even after multiple vibration tests. Each size did not loosen for 17 minutes in the high-speed vibration testing machine (NAS3350) of the Japan Quality Assurance Organization (JQA). Even if it does loosen, it will not fall off. The mechanism that prevents dropping lies in the spring coil; when tightening the nut, the coil expands and allows for tightening. It is also possible to re-tighten. Additionally, when attempting to loosen it, the coil wraps around the neck of the bolt, making it impossible to return. 【Features】 ■ It does not drop! ■ It can be stopped midway! ■ The tightening torque is sufficient with the appropriate torque! ■ It does not damage the bolt even when removing the nut! ■ Excellent workability due to its single nut design! *For more details, please request materials or view the PDF data from the download.

![[Technical Information] Why do screws loosen?](https://image.www.ipros.com/public/product/image/55f/2000509211/IPROS29721891067062031897.png?w=280&h=280)
[Technical Information] Why do screws loosen?
Why do screws loosen? This explains the causes of screw loosening!
The loosening of screws is related to a decrease in fastening force (bolt axial force), and the causes can be broadly divided into two categories: "non-rotational loosening of screws" and "rotational loosening of screws." When the bolt axial force is low or decreases, the number of cycles until bolt failure decreases, leading to a very dangerous situation. In combination with measures against non-rotational loosening, our 'HLN Hard Lock Nut' exhibits a powerful anti-loosening effect based on the principle of wedging. Therefore, you can use it with confidence without worrying about a decrease in fastening force. [Causes of Screw Loosening] ■ Non-rotational loosening of screws - Initial settling - Indentation loosening - Loosening due to micro-movement wear, excessive tightening, and other external forces - Loosening due to thermal causes ■ Rotational loosening of screws *For more details, please refer to the PDF document or feel free to contact us.

[Technical Information] Achieving anti-loosening effect based on the principle of "wedge."
Applying the principle of a "wedge" to nuts! A hard lock nut recognized by the world.
The cause of loosening screws lies in the play (clearance) of the threads between the bolt and the nut, and if this can be completely eliminated, it would achieve the ideal anti-loosening effect. Our anti-loosening effect utilizes the "wedge," which has been used in wooden construction for a long time. We have conducted extensive research and developed a product that applies the principle of this "wedge" to the nut. That groundbreaking product is the 'HLN Hard Lock Nut.' 【Features of the HLN Hard Lock Nut】 ■ Anti-loosening effect recognized worldwide ■ Torque and axial force management possible ■ Reusable ■ Easy and good workability ■ Contributes to significant cost reduction *For more details, please refer to the PDF materials or feel free to contact us.

![[Technical Information] Troubles Caused by Loosening: What is Bolt Failure?](https://image.www.ipros.com/public/product/image/db3/2000560032/IPROS42180665685764068528.png?w=280&h=280)
[Technical Information] Troubles Caused by Loosening: What is Bolt Failure?
Bolt damage/fracture occurs on the surface of the bolt, especially from the bottom of the thread valley where stress concentration is high!
The damage to screws and bolts can be broadly categorized into three types: "damage," "failure," and "fracture." Damage refers to the separation of a part of the material or the occurrence of permanent deformation, and it does not necessarily indicate a hindrance to use. Failure refers to the separation of a part or the whole of the material or the occurrence of significantly large permanent deformation that renders it unusable, while fracture refers to the separation of the material due to failure. In other words, damage or fracture of a bolt occurs on the surface of the bolt, particularly from the bottom of the thread valleys where stress concentration is high. For more detailed explanations, please refer to the related link page. 【Forms of Bolt Damage】 ■ Damage: Separation of a part of the material or occurrence of permanent deformation ■ Failure: Separation of a part or the whole of the material or occurrence of significantly large permanent deformation that renders it unusable ■ Fracture: Separation of the material due to failure *For more details, please refer to the PDF materials or feel free to contact us.

[Technical Information] About the Principle of Loosening: Basic Edition
A detailed explanation of "non-rotational looseness of the threaded part" and "looseness due to rotation of the threaded part"!
When physically defining the loosening of bolts and nuts, it can be defined as "the decrease in fastening force (bolt axial force)." So, what factors contribute to this decrease in fastening force? They can be broadly divided into two categories: "loosening due to non-rotation of the threaded part" and "loosening due to rotation of the threaded part." When considering methods to prevent loosening, it is necessary to examine these two factors. In the products of Hard Lock Industries, development focuses on how to prevent loosening caused by the rotation of the threads, resulting in overwhelmingly superior anti-loosening characteristics. [External force factors for loosening due to thread rotation] 1. Axial direction of the bolt 2. Direction perpendicular to the bolt axis 3. Direction around the bolt axis *For more details, please refer to the PDF materials or feel free to contact us.

![[Technical Information] How to detect looseness? (NAS Test)](https://image.www.ipros.com/public/product/image/8bc/2000560044/IPROS47300147668062805210.png?w=280&h=280)
[Technical Information] How to detect looseness? (NAS Test)
Testing that emphasizes the effects of accelerated (decelerated) environments and high-temperature environments! Introducing NAS testing!
The NAS test refers to the accelerated vibration test described in the U.S. aerospace standards: NAS (NATIONAL AEROSPACE STANDARD) 3350/3354, which is commonly known as the NAS test. Since the test is based on requirements for the aircraft industry, it emphasizes the effects of acceleration (deceleration) environments and high-temperature conditions. At Hard Rock Industries, the "impact vibration test in accordance with NAS3350/3354" is referred to as the NAS test. Additionally, the U.S. aerospace standards specify that the materials for applicable bolts and nuts are primarily heat-resistant alloys, and the lubricants used are also specified, along with various other criteria. To properly conduct the NAS test, it is necessary to adhere to all of these standards; however, for products intended for the Japanese market, tests that conform to the NAS test are generally conducted. *For more details, please refer to the PDF document or feel free to contact us.*

![[Technical Information] How to detect looseness? (Yunker Test)](https://image.www.ipros.com/public/product/image/a55/2000560048/IPROS49152938194157321064.png?w=280&h=280)
[Technical Information] How to detect looseness? (Yunker Test)
Continuously measure changes in axial force! We will explain the principles of the Juncker test in detail!
The Junker axial perpendicular vibration test is a test for the loosening of screws caused by repeated loads in the axial perpendicular direction. The principle of the Junker test is illustrated in the left diagram. By applying repeated forces perpendicular to the axis of the screw, it generates a loosening torque, allowing for continuous measurement of changes in axial force. In actual usage scenarios of screws and bolts, vibrations occur regularly and are a primary cause of loosening. The Junker test machine artificially generates vibrations in the axial perpendicular direction, which are prone to cause a decrease in axial force, for observation and verification. *For more details, please refer to the PDF document or feel free to contact us.*
