Washers are multipurpose fasteners that are vital in a variety of applications. In general, washers have two main functions: to distribute the pressure of the nut evenly over a surface without damage and to ensure that the nut is pressed against a smooth surface to reduce the chances of loosening over time. Ensure a tighter join with a lock washer, or pre-load it with a wave washer. You never think about washers until you run out of them, but they are necessary to have on hand.
