Herb Adams book is a really basic read. Helpful if you have no background or haven't done any research. Some dated information though so don't take it as gospel.

All of Carroll Smith's books are good reads. The Nuts,Bolts, and Fasteners one is a favorite of mine. Again, some dated info regarding products referenced in some cases but still really good information.
If you're really feeling froggy, Milliken's book is very highly regarded. It is the most technical, but really gets into suspension and chassis design, how tires work, etc... Little harder to find and definitely not cheap or light reading.
