DIN 982 Prevailing torque nuts with nonmetalic insert
DIN Standards are issued for various components, including industrial fasteners such as DIN 982 Prevailing torque nuts with non-metallic inserts. DIN 982 nuts are manufactured from Carbon steel, Alloy steel, Stainless steel, Steel, and Zinc plated steel. DIN 982 Nuts are available in various sizes, shapes, and materials.
Following are the specification of German DIN 982 Nuts:
Characteristics:
- Complies with ISO 7040; CSN 021492; UNI 7473.
- Strength class is 5, 8, and 10.
- Scratch resistance and Dimensional accuracy.
- RoHS compliance.
Advantages:
- DIN 982 nuts are lock nuts of the prevailing torque type that come with a non-metallic insert. This insert generates friction between the threads of the components, thereby enhancing the resistance to loosening.
- DIN 982 can be available in different finishes such as white or yellow zinc plated, auto black, chrome plating & others as per customer requirement.
Application:
- DIN 982 nuts are ideal for situations where the nut may become loose due to motion or vibration.
- DIN 982 is also effective in preventing liquid seepage, such as oil, water, petrol, and paraffin, from entering the bolt thread.
- DIN 982 nuts are suitable for demanding tasks and can be utilized in heavy-duty applications.
