ISO 7041 Hexagon locknuts with non-metallic inserts - detailed description and industry solutions

ISO 7041 is a locknuts standard known as "low profile nuts" or "nylon ring nuts." The difference between these nuts is that they have a nylon ring that provides additional friction to make the nut tighter.DIN985 locknuts are widely used in machinery manufacturing, electronic equipment, automotive parts, and other fields. This nut is suitable for high-strength fastening and can be used many times.ISO7041 locknut is a kind of locknut standard widely used in machinery manufacturing, electronic equipment, automobile parts, etc. It has the advantages of quick and easy installation, corrosion resistance, being able to be used many times, providing extra friction, and avoiding loosening. However, attention should be paid to the correct installation method, size selection, and thread type.ISO7041 Non-metallic Insert Hexagonal Lock Nut is a fastening part commonly used for mechanical connection and widely used in industrial fields. It has many advantages, such as simple structure, easy installation, long service life, and so on, so it is highly favored.

Versatile yet economical, these are the most commonly used locknuts. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.

High-Strength Steel

Rated Grade 8, Grade C, or Class 10, these locknuts are about 25% stronger than medium-strength nuts. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.

Zinc Yellow-Chromate-Plated Steel—These nuts are suitable for most wet and outdoor environments and have a more durable finish than clear zinc plating. However, they won't withstand the harsh chemicals that stainless steel can.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Black-Oxide Steel—Typically chosen for their appearance, these nuts have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Black Corrosion-Resistant-Coated Steel—These nuts combine a finished appearance with the rust resistance of stainless steel. To hold up in wet and outdoor environments, the coating has been tested to extreme standards, including 1,000 hours of salt spray resistance. It is also known as black luster.

Steel—These locknuts are best for dry environments since moisture will cause them to rust.

Definition of ISO7041 hexagon locknuts with non-metallic inserts

ISO7041 non-metallic insert hexagon locknut is a special nut used to secure and lock the connection. Compared with traditional metal nuts, they are made of non-metallic materials, usually nylon, plastic, or rubber. These materials have high wear resistance, chemical resistance, and insulating properties.

Heavy-Profile Nylon-Insert Locknuts： About 10% wider and taller than standard-profile locknuts, these handle heavier loads by distributing them over a larger area. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.

The national standard of non-metallic insert hexagonal locknuts and related standards.

The ISO7041 national standard for non-metallic insert hexagonal locknuts is stipulated in the Specification for Non-Metallic Insert Self-Tapping (Drilling) Wire. The standard details the classification of non-metallic insert hexagonal locknuts, size, technical requirements, test methods, and inspection rules. In addition, some related industry standards, such as JB/T 5748-2005, "Aviation with non-metallic inserts self-tapping (drilling) wire and hexagonal thin plate low-columnar semi-metallic nuts," and so on.

-First, choose the right size according to the actual demand. Standard-size DIN985 locknuts usually have threads from M2 to M24.

-Secondly, choose the material; DIN985 locknuts are usually made of carbon or stainless steel, among which stainless steel is more corrosion-resistant.

-Finally, determine the level of firmness needed for locking. If you need a more solid tightening strength, you can choose DIN982 locknuts.

Structure and working principle of non-metallic insert hexagonal locknuts

Structural characteristics and components

A non-metallic insert hexagonal lock nut is a device used for fastening threaded parts; its main structure consists of the following components:

a) Shape outer diameter: the shape of the non-metallic insert hexagonal lock nut is hexagonal, and its outer diameter is usually formulated using international standards.

b) Six apertures: Inside the nut are six apertures distributed in symmetrical positions. These apertures serve the purpose of transferring the load-carrying capacity equally between the corresponding parts.

c) Internal Cavity: An internal cavity exists in the center area to accommodate and fit the threads on the connected parts.

ISO7041 non-metallic insert hexagonal locknuts working principle and method of use

The working principle of the non-metallic insert hexagonal locknut is based on its unique structural design. When mounted on a part with a fitting thread, a preload is applied by rotating the accumulator without loosening or opening the overall connection. Here is how this locking mechanism works:

a) Installation: First, the threaded parts are inserted into the inner cavity of the non-metallic insert hexagonal locknut to ensure that they fit each other. The nut is then turned to the desired position manually or by using the rotational torque of a wrench.

b) Preloading: When installed, the non-metallic insert hexagonal locknut is subjected to a degree of torque, creating a tight fit between the part and the nut. This increases the friction, achieving a preloaded condition.

c) Locking effect: Once a tight joint is formed, the non-metallic insert hexagonal locknut will always maintain its preloaded state when a load is withdrawn or applied. The structure is designed so that its internal micro-geometry produces a spring-like deformation.

d) Disengagement: If the connection needs to be dismantled or the preload adjusted, the locking effect can be disengaged by simply turning the non-metallic insert hexagonal locknut counterclockwise.

6.ISO7041 non-metallic insert hexagonal locknuts common problems and solutions

When using non-metallic insert hexagonal locknuts, you may encounter some common problems. These problems and their corresponding solutions are listed below:

a) Loosening and Failure: If non-metallic insert hexagon locknuts are prone to loosening or failure, check that the installation process complies with standard requirements and verify that the proper size and type have been correctly selected.

b) Overload and wear: If non-metallic insert hexagonal locknuts are subjected to loads over their rated loads, wear or structural deformation may result. Before use, ensure the selected type can withstand the loads in the intended application.

c) Effect of Temperature Changes: Temperature changes may affect the performance of non-metallic insert hexagon locknuts. Unique models of high-temperature resistant materials must be selected in high-temperature environments to ensure optimum performance.

d) Cleaning and Maintenance: Non-metallic insert hexagonal locknuts should be cleaned and maintained regularly to ensure consistent performance. In addition, the necessary lubrication operations should be carried out as required.
