Our AREA spring washers are designed to exceed all applicable AREA specifications.
These high strength heavy lock washers are made from high grade steels and heat treated to provide years of service under the most extreme conditions of shock, vibration and environment.
The ductility of the lock washer shall be determined by twisting one end of a finished spring lock washer through 90 degrees without sign of fracture, and the other end is held securely.
We have most of the spring lock washers in stock with the below sizes.
