Flat washers are the most common and are used in industry, construction and machinery, as well as other applications where even load and pressure distribution is required. They are all manufactured in steel, brass, A2 and A4 stainless steel. They are also available uncoated, black coated, zinc plated and hot dip galvanised, with respective sizes and lengths.
How to choose the right flat washer?

Flat washers have a round shape that allows an even load distribution on the base material. They are ideal for reducing friction between the fastening element and the surface, as well as preventing screws from loosening or being exposed to vibrations.

At CHAVESBAO we have flat washers in different sizes and thicknesses to suit a wide range of applications. The choice of each one will depend on the area of application and the diameter of the bolt to ensure a consistent fixing.

Materials of construction

Flat washers have a number of characteristics and functionalities depending on the area of application so that, depending on the environment and the materials used, the appropriate product can be selected:

  • Washers made of steel have different coatings – black, zinc-plated and hot-dip galvanised – which protect the material against corrosion and rust.
  • High-strength steel washers are suitable for extreme environments.
  • Washers made of brass have a high wear resistance.
  • A2 stainless steel washers are used in outdoor applications and A4 stainless steel washers are used in salt water environments, among other uses.
