It is something we realize that no engineering project is like another. This is why we do custom taper washers as per your drawings or specifications or special materials. Whether a standard dimension or finish is not going to fit, we can produce custom solutions, whether it is an alternative alloy or non-standard slope angles or special surface finish, to smoothly fit your structural or mechanical requirement.
Where structural incompatibility or non-parallel surfaces are involved, taper washers are important. They are often applied in the bottom of nuts or bolt-heads in connecting into channel sections, I-beams or other supporting structures, to correct alignment, to share the load and provide a smooth interface. As an example, one manufacturer suggests that their washers are created to make the bolt assembly fit on the support structures evenly, in I-beams, U-beams and American Standard beams.
