The F436 flat washers are meticulously designed to be placed between the connected piece and the nut. These flat metal rings serve a crucial role in safeguarding the surface of the connected member from the potential damage caused by the nut, while also distributing the pressure exerted by the nut evenly across the connected member, ensuring enhanced durability and stability.
