The F436 flat washers are ingeniously designed to be positioned between the connected piece and the nut, serving a crucial role in the assembly. Typically fashioned as a flat metal ring, they effectively safeguard the surface of the connected member from damage by the nut. Additionally, they expertly disperse the pressure exerted by the nut, ensuring a more even and secure connection.
