The F436 flat washers are strategically placed between the connected piece and the nut. Primarily, these flat metal rings serve as a safeguard for the surface of the connected components against the nut's influence. Additionally, they effectively disperse the pressure exerted by the nut, ensuring the connected member remains intact.
