Washers

Washers on hi-fi spikes are used to protect the floor or surface on which the spikes rest from damage. They distribute the pressure generated by the sharp points of the spikes evenly over a larger area, preventing scratches, dents or other damage to sensitive floors such as wood or tiles.
In addition, washers provide extra stability by preventing the spikes from pressing into the floor or slipping. This helps to keep the position of the speakers or audio components precise, ensuring consistent sound reproduction.
