Brass flat washers is their ability to distribute pressure evenly, ensuring a tight seal and preventing damage to the underlying surface. These washers are commonly used in plumbing systems, automotive assemblies, electrical connections, and many other applications where sealing and protection are crucial.

In plumbing systems, brass flat washers are often used in conjunction with brass fittings to create a watertight seal. The corrosion resistance of brass ensures that the washer remains effective even in moisture-prone environments. Additionally, the electrical conductivity of brass makes these washers ideal for grounding applications, helping to prevent electrical shocks and ensure the safety of electrical systems.
