This kit from RS PRO contains 1090 plain brass washers supplied in a moulded plastic compartment storage case. Brass washers are commonly used in plumbing, electrical systems and a variety of mechanical devices such as gears, bearings or doorknobs.
You can use the plain, flat washers included in this kit with standard metric fasteners with M10, M2, M3, M4, M5, M6 and M8 size threads. They are made of brass and have a nickel-plated finish, which makes them resistant to corrosion and ensures they will last longer.
These washers meet the DIN 125-1A standard for flat washers, meaning they are grade A washers with a hardness of up to 250 HV, designed for use with hexagon head bolts and nuts. They also comply with Restriction of Hazardous Substances (RoHS) standards, so you can be sure they include only minimal amounts of any harmful substances.
