    How to choose a washer:

    It is important that your washer is compatible with your fasteners and your chosen application. You should consider the following information when choosing a washer.

    • Size - It is important to ensure that your washer is compatible with other fasteners you are using. The screw or bolt is usually measured in metric dimensions, such as M10 (10mm) or M8 (8mm).
    • Material - Washers are primarily made from stainless steel or brass. Stainless steel washers are popular due to its durability and corrosion resistance. However, other materials are available, such as ceramic. Washers come in a variety of finishes too, such as chrome and nickel plated.
    • Shape - The majority of washers are round to match the round head of a screw of bolt. You can also buy square washers for use with bolts with a square head.
    • Thickness - there is a range of thicknesses available. Thicker washers can provide extra strength.
