Who still uses lock washers when designing machinery?

As a many year designer of food processing equipment we are planning to start eliminating all lock washers and most flat washers from our designs.


This is to improve sanitation of our machines, as well as customer requests.


There are also studies that demonstrate that lock washers actually cause fasteners to loosen more easily.


What has been your experience with this issue?
