A bowed snap-disc includes inner and outer perimeters that provide the disc with operating characteristics not found in comparably sized discs. At certain points along its circumference, the inner perimeter extends farther from the disc's center than certain other points of the disc's outer perimeter. This provides the disc with a unique combination of spring constant, compressive force, deflection and coefficient of compliance. The disc is particularly useful as a small, flat compression spring; a shaft or bar locking element; tightness indicator for a threaded fastener; or a lock washer.
