M12 - Spring Washer Square Section Type A DIN 7980 - Phosphor Bronze - Pack of 25

These square section M12 spring washers are manufactured from high quality steel and feature a phosphor bronze finish. Type A Spring washers are specifically engineered for applications where there is a need to prevent loosening fasteners due to vibration or torque. Their helical shape allows them to exert a continuous force between the fastener's head and the substrate, maintaining tension and improving the reliability of the joint. These washers are ideal for use with metric threaded fasteners in a wide range of applications, from heavy-duty industrial settings to everyday DIY tasks. They conform to the DIN 7980 European Standard specification.
