Table Washers Self Colour

Table washers are similar to flat washers, ut are usually (but not always) used when referring to imperial sized washers instead of metric.

Self coloured finishes have no protection against corrosion, and are more suited for use in internal joinery applications. Self colour finishes have no definitive colour and can vary with the effects of natural oxidisation and weathering, from a bright zinc finish to a dark black colour. Before being used in exterior environments, they should be coated or painted with a protective covering.
