Flat washer with large outside diameter DIN 9021, A2, M10

The basic purpose of flat washers is to prevent loosening of bolts and nuts, which is particularly important in applications subject to vibration and torque, such as the solar industry. It has the characteristic of maintaining tension and tightness between the bolt and washer. They are ideal for solar panel systems where screws tend to loosen over time.

Stainless steel lock washers provide extra protection against loosening of the bolts. High quality stainless materials ensure long life and reliability of the fixing. They are corrosion-resistant, providing a stable and timeless fixing when installing solar modules.
