I do some equipment restoration as a hobby. Looks are important. Take a look at these two screws. One is shiny silver, the other is darker. The ones in the equipment are the darker ones. Most of the screws I buy are the shiny ones. Since I didn't buy either of the screws in this picture, I don't know anything about them. What finish is on the darker ones? I'm sure they're the cheapest ones available. The pictures on the McMaster-Carr website or representative, so I can tell anything from those.
Again, I'm positive these screws are nothing special. The equipment is electronic, used inside, and under no physical stress.
