Choosing the right type of fastener can be confusing as some metals don’t work well together. They can “attack” other metals which will cause at best discoloration and at worst structural failure.
And it is not just differing metals touching each other that can cause issues. Mere proximity must be considered.
Rainwater runoff from a reactive metal to another can wreak havoc. It is therefore very important to keep galvanic reaction potential in mind when planning the design of your building.
