Fastener selection may sound easy, However there are so many variables and choices that improper fastener selection is likely to happen. To choose the proper fastener for the job getting a baseline knowledge of different materials and coatings is a good start.

I came across an excellent explanation in my searches and figured it could be a good resource for others wanting to know about fasteners.

There is MUCH more that can be said and each fastener type could have pages written about it, however this should get you started on your way

 

Thanks for the link. It was interesting, but I don't think it helps one much in choosing the appropriate fastener for a given application. You are correct that MUCH more should be said. From reading the link I would not have much of a clue as to what material, heat treatment, coating and especially size and torque/clamping force I should choose for something like a main stud. IMO that would be much more useful. Thank goodness for folks like ARP.

So is Inconel a good head stud material for high-end engines? Why?
