The F436 flat washers serve as essential components placed between the connected piece and the nut. Typically designed as flat metal rings, these washers play a crucial role in protecting the surface of the connected components from damage caused by the nut, thereby effectively dispersing the pressure exerted by the nut across the connected member.
