Are you wondering whether a lock washer can work with a lock nut? In this Lock washer vs lock nut review, we explain the differences of the two washers and see if they are compatible.
I restore automobiles for a living in my home garage, I have always had issues with the washers I used. They did a good job holding the assembly at first but with time, problems arose. My clients kept coming back with complaints about wobbly or leaking components. I though using standard washers was fine to provide the needed lock pressure between fastener and surface. As I did my research, I realized I was using the wrong washers. I needed washers that could dig into the bold head and the surface for added friction. This is how I landed on lock washers and lock nuts.
