What is Plain Washer?
Plain Washer is a thin plate (typically disk-shaped, but sometimes square) with a hole that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Additionally, a plain washer may be used when the hole is a larger diameter than the fixing nuts. Specifications for standard metric flat washers were known as DIN 125 and replaced with ISO 7098.
Size
Applications
Washers are placed on a bolt between the nut (on the threaded end) and the bolt head to distribute the load of a threaded fastener. Other uses are as a spacer,spring, wear pad, preload indicating device,locking device, and to reduce vibration.
Surface treatments
▲Black plated
Black is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention.

▲Zinc coated
Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.
▲HDG
he main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating. Hot-dip zinc has good corrosion resistance, sacrificial protection for steel substrates, high weather resistance, and resistance to salt water erosion. It is suitable for chemical plants, refineries and coastal and offshore operating platforms.
