The F436 flat washer is an essential component that is meticulously placed between the connected piece and the nut. Typically, this flat metal ring serves the critical purpose of protecting the connected member's surface from the nut. Additionally, it evenly disperses the pressure exerted by the nut, ensuring the integrity and longevity of your assembly.
