Clamping nut (mechanical hydraulic type) made by Hilma, Germany

Clamping nut (mechanical hydraulic type) made by Hilma, Germany

You can safely perform the work of fastening bolts and nuts. Large-sized bolts can be securely fixed with a hex wrench using a mechanical hydraulic system.

When fixing a large-sized "standard nut" to a bolt, it was necessary to use a "long handle" to tighten the nut with "great force." This required a wide space when tightening with the "long handle," and there was a risk of the handle coming off, which could lead to injuries for the operator or damage to the equipment. By using the HILMA company's clamping nut (mechanical hydraulic type), you can achieve "great tightening force" simply by tightening with a "hex wrench," as the built-in piston activates. Additionally, there is an optional tightening force checker that alerts you when the tightening force reaches its maximum by popping out a pin. Applications include fixing equipment, securing molds in press machines, holding workpieces during processing, and providing strong fastening in narrow spaces or places where hydraulic power cannot be used. For more details, please contact us or refer to the catalog.

Anti-loosening nut "Muscle Nut" [Does not loosen regardless of time!]

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 tightened loosely, achieving 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?

[Technical Information] Why do screws loosen?

Why do screws loosen? This explains the causes of screw loosening!

The loosening of screws is related to the 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-motion 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."

[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 nuts. That groundbreaking product is the 'HLN Hard Lock Nut.' 【Features of 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 document or feel free to contact us.

[Technical Information] Troubles Caused by Loosening: What is Bolt Failure?

[Technical Information] Troubles Caused by Loosening: What is Bolt Failure?

Bolt damage/breakage occurs on the surface of the bolt, especially from the bottom of the thread groove where stress concentration is high!

The damage to screws and bolts can be broadly classified into three categories: "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 imply 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 material breaking apart and separating. In other words, the damage/fracture of a bolt occurs on the surface of the bolt, particularly from the bottom of the thread valley where stress concentration is high. For a more detailed explanation, 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: Material breaks apart and separates *For more details, please refer to the PDF materials or feel free to contact us.

[Technical Information] About the Principle of Loosening: Basic Edition

[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 "a decrease in clamping force (bolt axial force)." So, what factors contribute to this decrease in clamping 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 anti-loosening measures, 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, and they possess overwhelmingly superior anti-loosening characteristics. [External force factors of 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)

[Technical Information] How to detect looseness? (NAS Test)

Testing that emphasizes the impact 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 referred to as the NAS test. Since the test is based on the aviation industry, it emphasizes the effects of acceleration (deceleration) environments and high-temperature environments. 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 primarily focus on heat-resistant alloys for the materials of applicable bolts and nuts, and specify the lubricants to be used, along with various other criteria. To properly conduct a NAS test, it is necessary to adhere to all 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? (Junker Test)

[Technical Information] How to detect looseness? (Junker Test)

Continuously measure changes in axial force! We will explain the principles of the Junker 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 in the perpendicular direction to the axis of the screw, a loosening torque is generated, and the changes in axial force are continuously measured. In actual usage scenarios of screws and bolts, vibrations occur regularly and are a primary cause of loosening. The Junker testing machine artificially generates vibrations in the axial perpendicular direction, which are prone to cause a decrease in axial force, allowing for observation and verification. *For more details, please refer to the PDF materials or feel free to contact us.*

[Technical Information] Basic Knowledge of Understanding Looseness: What is Torque and Axial Force Management?

[Technical Information] Basic Knowledge of Understanding Looseness: What is Torque and Axial Force Management?

How to determine the tightening torque necessary to manage the appropriate axial force! Introducing a simple calculation formula.

When fixing the joined components, the types of fastening screws include bolts and nuts. Axial force refers to the force that occurs when a bolt is tightened; the bolt tightening area is pulled in the axial direction and stretches very slightly. The reactive force that tries to return it to its original state is the axial force. If the axial force is not within the appropriate range, it can cause loosening or lead to the destruction of the joined components, making daily management of proper tightening torque and axial force important. Now, to determine the necessary tightening torque for managing the appropriate axial force, it can be calculated using a simple formula. We provide detailed information on this topic on our technical information site, "Screw Fastening Technology Navigation," which contributes to solving screw fastening challenges. Please check it out through the related link. *For more details, please feel free to contact us.
