Double serrated lock washer DIN25201 washer

The main usage of DIN25201 washers is in the assembly of bolted joints in industries such as automotive, construction, and machinery. These washers are specifically designed to prevent the loosening of bolts and nuts due to vibrations, thermal expansion, or other external forces.

DIN25201 washers have a unique design with internal teeth that bite into the mating surface of the joint, providing a locking effect. This helps to distribute the load evenly across the joint, improving the integrity and reliability of the connection.

These washers are commonly used in applications where there is a risk of bolt loosening, such as in high-vibration environments or when dealing with critical connections that require extra security. They are often used in conjunction with standard flat washers and locking nuts to provide a secure and durable joint.
