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.
