Product Description

Product Description

. Product Overview
DIN985 is a non-metallic insert hexagon anti-loosening nut. Its feature is that a layer of nylon material (usually nylon 66) is embedded around the inner thread of the nut. The anti-loosening effect is achieved through the elastic deformation and friction of the nylon material. This type of nut is widely used in industries such as machinery, automobiles, electronics, and construction, and is particularly suitable for applications that require high anti-loosening performance. 
#### 2. Product Features
- **Outstanding Anti-loosening Performance**: When the bolt is screwed in, the nylon insert is deformed under pressure, filling the thread gap and increasing the rotational resistance, effectively preventing loosening.
- **Corrosion Resistance and Insulation**: Nylon material has excellent resistance to acids, alkalis, and corrosion, and is insulating and non-conductive, making it suitable for use in special environments.
- **Lightweight Design**: Compared with traditional metal nuts, nylon insert nuts are lighter in weight, making them suitable for applications where weight is a concern.
- **Easy Installation and Disassembly**: They can be installed and removed using tools such as adjustable wrenches, open-end wrenches, and socket wrenches, with simple operation. 
#### 3. Materials and Specifications
- **Materials**: The main body of the nut is typically made of carbon steel or stainless steel (such as 304, 316), and the nylon insert is made of nylon 66.
- **Specifications**: Compliant with DIN985 standard, fine thread is available as an option. With a smaller pitch, it offers stronger self-locking performance and is suitable for precision applications. 
#### 4. Application Fields
- **Mechanical Industry**: Used for connecting equipment in high-vibration and high-impact environments to ensure reliable fastening.
- **Automotive Industry**: Suitable for body structures, engine components, and other areas requiring anti-loosening.
- **Electronics and Electrical Appliances**: Applied in circuit board fixation, device housing connections, etc., with insulating properties.
- **Construction Industry**: Utilized in steel structure connections, track fixation, etc., adaptable to complex environments. 
#### 5. Precautions
- **Prevent Nylon Aging**: Pay attention to the storage environment's temperature and humidity to prevent the nylon material from hardening or aging.
- **Installation Direction**: Ensure that the bolts are inserted vertically during installation to avoid damage to the nylon insert or a reduction in the anti-loosening effect. 
#### Summary
The DIN985 nylon lock nut, with its outstanding anti-loosening performance, corrosion resistance, and lightweight design, has become an important choice in industrial fasteners.
