Flat Washers Brass

Brass Flat Washers

Standard Round Flat Washers in Brass


  • Brass flat washers are made of Dezincification resistant (DZR or DR) brass
  • Normal brass flat washers do not meet this standard and have high corrosion risk
  • Brass flat washers are suitable for high water temperatures, deviating water qualities (soft water) or where chloride is present
  • DZR-brass is excellent in water boiler systems

Please note that color and sheen may vary for brass and silicon bronze fasteners.
