Contact / Conical Washer

Contact / Conical Washers are specially designed spring-type washers that provide elastic force to maintain bolt tension under load. Their conical shape allows controlled deflection, improving the security of bolted joints against loosening. Manufactured to ASTM and DIN standards, they are widely used in heavy-duty and high-vibration environments. These washers ensure load distribution, prevent fatigue loosening, and enhance joint reliability.  They are commonly used in structural steelwork, railways, wind turbines, automotive, and heavy machinery.
