The F436 flat washer is strategically positioned between the connected piece and the nut. Typically crafted as a robust flat metal ring, its primary function is to safeguard the surface of the connected member from potential damage caused by the nut. Additionally, it effectively disperses the pressure exerted by the nut, ensuring a secure and stable connection.
