吊りボルト専用脱落防止ナット　「マッスルナット」

吊りボルト専用脱落防止ナット　「マッスルナット」

シングルナットで、単体の取り付けで緩み止め＆脱落防止が可能

吊りボルト専用脱落防止ナット「マッスルナット（赤色チューブ）」は、脱落しません。 一般的な吊ボルトは、JIS規格ではなく、施行性や大量使用用途に向けたコスト面重視のため、 ボルトねじ有効径が細くなっています。そのため、市販のナットでは強く締めても振動等に耐えられず緩んで脱落してしまいます。 その緩みを解消するため、吊ボルト専用のマッスルナットを開発しました（六角ボルトのW3/8、W1/2には使用できません）。 締付けは施行性を良くするため、手でも締められるよう緩めにしてあります（それでも緩めトルクは、W3/8で4.5N・m以上です）。 また、マッスルナットは締付け途中で止めておくことも出来ます。 高所での利用を考慮し視認性を良くするため、赤色チューブを使用しています。 詳しくはカタログをダウンロードしてください。

Selection of Push Nuts for Improving Work Efficiency

Selection of Push Nuts for Improving Work Efficiency

Knowledge for selecting other accessories and parts: Reducing labor and costs with push nuts.

【Before】 ■Rivet Specification When connecting the lot rod for the panel to the handle's stop pin, it is usually riveted by hammering a rivet pin, but this process takes time and effort. ↓ 【After】 ■Push Nut Specification By using a push nut instead of the riveting process, it can be easily fixed just by press-fitting the push nut onto the pin shaft. This prevents excessive riveting from the riveting process and improves appearance. *For more details, please refer to the catalog or feel free to contact us.

Hard rock nut / Hard rock bearing nut

Hard rock nut / Hard rock bearing nut

HLN (Hard Lock Nut) / HLB (Hard Lock Bearing Nut)

The Hard Lock® nut, born in Japan and growing worldwide, possesses a strong anti-loosening effect, excellent workability, and ease of attachment and detachment that other lock nuts do not have. Could the principle of a wedge be applied to anti-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

[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

[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

[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.

[Technical Information] About the Structure of Screws

[Technical Information] About the Structure of Screws

We will provide a detailed introduction with diagrams and tables about the commonly used metric threads for fastening!

In the fastening of mechanical structures (screw joints), 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 a 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 on the item, and tightening the screw. A screw joint is defined as the entire structure that has a screw fastening part or a part of a structure that includes a 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.

[Technical Information] Regarding Tightening Stress

[Technical Information] Regarding Tightening Stress

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 connection can be broadly divided 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 Navigation," which contributes to solving issues related to screw fastening, confirms the stresses generated inside the bolt during tightening and provides detailed information on the damage to screws when the tightening torque is too high. Please take a look through the related links. *For more details, feel free to contact us.

[Technical Information] On Metal Damage: "Corrosion"

[Technical Information] On Metal Damage: "Corrosion"

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 very small gaps on the order of microns; "grain boundary corrosion," where crystal grain boundaries are preferentially corroded; "erosion corrosion," which involves corrosion accompanied by the action of fluid wear; and "high-temperature oxidation," which occurs when exposed to high-temperature air or steam. On our technical information site "Screw Fastening Technology Navi," which contributes to solving issues related to screw fastening, we introduce the three main forms of corrosion (uniform corrosion, pitting corrosion, and galvanic corrosion). Please take a look through the related links. [Contents] ■ Main forms of corrosion - Uniform corrosion - Pitting corrosion - Galvanic corrosion ■ Special corrosion cracking - Stress corrosion cracking - Hydrogen embrittlement cracking *For more details, please feel free to contact us.
