FAN WASHERS ARE USED TO PREVENT THE LOOSENING OF SCREWS
 

Convenient, safe and long-established, the screw connection is the most commonly used assembly method. This does not always prevent a screw from running the risk of loosening, especially under the effect of vibrations or rust! The fan washer was invented to avoid this kind of inconvenience. Discover the advantages and ubiquitous applications of Würth’s fan washers for professionals.
 
 

WHEN TIGHTENING, THE TEETH ARE PLANTED IN THE SCREW HEAD AND IN THE NUT
 

The fan washers are fasteners for safety. Note that the diameter of the washer must match the size of the screw head to achieve the desired effect. The process is simple:


• place the washer between the screw head and the corresponding component (a nut, for example)

• screw on the fastener

• the outer or inner teeth of the washer will then penetrate the screw head and the nut, this will increase the strength of the assembly and prevent any unexpected loosening.
  
 

WASHERS MADE OF STAINLESS STEEL OR ZINC PLATED, WIDELY USED IN ELECTRICAL ENGINEERING
 

This method of fixing of course has its limits, and fan washers are today rarely employed in mechanical engineering. They nevertheless offer considerable advantages in the field of electrical engineering, the numerous points of support obtained making it possible to increase the conductivity of the assembly. Also, remember to check the material of your fan washer before making your choice, noting that:


• simple steel is more susceptible to rust than stainless steel
• galvanized surfaces offer increased protection against corrosion
• the bare and untreated fan rings do not offer any additional protection.
