Spring washer is a mechanical fastener designed to prevent loosening of bolted joints through spring tension and friction.
A spring washer, specifically a disc spring or Belleville washer, is a conical-shaped washer that applies a continuous spring force against a nut or bolt head. When compressed during tightening, it creates axial tension that counteracts vibrational loosening in mechanical assemblies. In coupling mechanisms, it maintains preload on connecting elements, ensuring torque transmission reliability.

It creates continuous spring pressure that increases friction between threads, resisting rotational forces from vibration or thermal cycling.
Not recommended, as repeated compression cycles can cause spring fatigue and loss of tension, compromising locking effectiveness.
