If you are rebuilding your bike, you may have seen or heard about anodised bolts but did not know all the fuss is about. Maybe you would like to know what colour you can get anodised bolts in, or what type of metal they are available in. Hopefully this blog post will clarify some of your questions regarding anodised nuts and bolts.
The first decision to make is what material the bolts and nuts should be manufactured from. If you are looking for anodised fasteners your choices are limited to aluminium and titanium. This is due to the fact that not all metals can be anodised.
If the fasteners is to be used in high stress applications such as chassis fixing or suspension mounts, Titanium should be chosen as it has a stronger tensile strength. If you are fastening dials or the petrol cap for example, aluminium fasteners can be used.
The second important consideration when choosing the type of anodised bolts is the colours that are possible in the different metals. Normally aluminium bolts will have a wider selection of colours than the Titanium counterparts. This should however not interfere with your safety considerations, if the chosen colour is not available in Titanium for a high high impact application, rather opt for a silver or alternative available colour in Titanium or stainless steel.
A few people may wish to avoid bolts that are anodised a colour and opt for the normal silver ones. This is especially true when doing exact replicas or similar motorcycles. Even in this case, the plain silver anodised fasteners will have an advantage over plain steel bolts, and that is they do not tarnish or rust.
Rust is not an issue using bolts that are anodised because of the chemical process they are put through. With out discussing the technicalities of anodising, the parts are placed into a chemical solution with current running through the solution and parts. This process also hardens and seals the metal, which is why it will not show signs of tarnishing or rust.
