Cadmium Plated Fasteners
Cadmium plated fasteners are most popular plated fasteners because it provides excellent corrosion protection from salt water and other kinds of salts, plus this type of plating was relatively inexpensive. Cadmium Plated Stud Bolts have a comparatively low and fairly consistent coefficient of friction. Cadmium plating’s finish luster does not tarnish or fade. Cadmium is relatively easy to electroplate onto high strength steel, and for those steels whose strength is too high to tolerate the hydrogen embrittlement from electroplating.
Cadmium coatings are particularly useful in the electrical, electronic, aerospace, mining, offshore, automotive and defence industries where they are applied to bolts and other fasteners, chassis, connectors and like components.

Generally, cadmium plating done on any object makes it resistant to corrosion. This is why cadmium plated bolts can be highly suitable for machineries that are to be installed in harsh environmental conditions. This is why aviation, aerospace and military defence industries opt for fasteners with this coating.
When cadmium coating is done on any object, the adhesive properties of the object get improved. This means that when an object is coated with this substance, the surface becomes more bondable to adhesives that are commonly used in such applications like aircraft manufacturing.
This coating can effectively improve the lubricity and this is why it is recommended that people looking for eye bolt anchor can go for the one with this type of coating. This can be the ideal choice for moving parts of machines, which in turn work towards prevention of galling and it will also bring down friction, which will be of high importance in the functioning of machinery, where metal surfaces commonly touch each other.
