Galvanized bolts are just like any other bolt but they’re reinforced with an electrochemical procedure called galvanization. This procedure produces a bolt more powerful, able to withstand the harshest weather conditions, particularly for bolts used in marine applications to prevent corrosion.
Bolts are electrodeposited with a thin layer of a metal made from steel to prevent rust. Some bolts of the sort are employed with a protective metallic coating in their bottoms; these bolts are known as hot dip galvanized. The only difference is that these bolts don’t experience the exact electrochemical disposition that a normal galvanized bolt undergoes.

Galvanized bolts as the name suggests are created through the process of galvanization. This term originally refers to the administration of electric shocks in the 19th century. It was Luigi Galvani’s idea, hence the name, to affect matter by an electrical shock that was later utilized in psychiatry through ECT.
The term was later on used to refer to electrodeposition that is what happens through galvanization, or just, zinc coating. So bolts are protected by a coating of steel iron or alloy with zinc. This is mostly done to prevent galvanic corrosion, or just rusting of the bolt.
So galvanized bolts are just bolts which are metal protected to resist corrosion. Zinc is usually consumed by rust as a sacrificial anode therefore that it doesn’t reach the exposed steel of the bolt. Simply painting a bolt zinc is futile if not galvanized. The main reason is that warm zinc coating creates a thicker, much durable coating a simple paint coating doesn’t achieve.
Electroplating on the other hand just generates a thin coating of zinc which produces a bolt shiny and nice. Bolts that are hot dip galvanized often get a grayer surface.
