Products Description
why choose DIN 9021 Flat Washers?
DIN 9021 Flat Washers are a type of washers that comply with German Industrial Standards (DIN) and are used in the fields of mechanics and engineering. This type of washer is round in shape with a flat outer surface that can evenly disperse pressure and reduce friction and wear. DIN 9021 flat washers are usually made of metal materials such as carbon steel, stainless steel or brass to meet different application requirements. During installation, DIN 9021 flat washers are often used with bolts or nuts to ensure a tight connection between fasteners.
Products Application
Application scenarios
complex and harsh engineering environments
DIN 9021 Flat Washers are made of steel with high strength and hardness. They can adapt to high-intensity working pressure of various large-scale mechanical equipment.
Adapt to high-frequency applications
Since DIN 9021 galvanized flat washers have excellent electrical conductivity, they perform very well in certain high-frequency transmission situations and become one of the solutions.

Products Description
difference between DIN125 and DIN 9021 Flat Washers
|
Model |
DIN 9021 Flat Washers |
|
|
Outer diameter size |
Determined by nominal diameter |
Larger outer diameter than ordinary flat washers |
|
Application occasions |
DIN 125 steel flat gasket washers are suitable for general metal surfaces as they reduce friction and facilitate tightening of nuts. |
When screwing non-metallic parts to protect the surface of the material from damage, DIN 9021 Big flat washers are often used because they have a larger pressure-bearing area and can prevent the surface of the soft parts from being damaged during tightening. |
|
Structural features |
DIN 125Normal flat washers are usually thin pieces of various shapes with a hole in the middle. The size of this hole is generally determined according to customer requirements. |
This big flat washers may be different in structure to accommodate their greater load-bearing capacity and protective function. |
|
Performance differences |
Average load-bearing capacity and smoothness |
Has a larger load-bearing pressure area, which can better disperse the pressure and prevent the surface of the connection from being damaged during tightening. In addition, the flat washer has a smooth surface, which helps to reduce friction when tightening the nut. |
|
Applicable bolt specifications:The specifications of these two flat washers usually match the specifications of the bolts and are affected by the size of the bolts. |
