Don’t Overlook the Washer: A Small Part with a Big Job

Keywords: Washers, FastenersA washer is a thin plate (usually with a hole) used in conjunction with a nut and bolt. Its primary functions are to distribute the load of the fastener over a larger area (preventing surface damage), act as a spacer, and in the case of spring washers, provide a locking force to resist vibration. Using the correct washer—flat, lock, or fender—enhances joint performance and prevents common issues like loosening or embedding into soft materials.
