The black finish comes from a chemical "conversion coating" for metal where the surface is subjected to an electrochemical or chemical process leaving a coating on the metal and converting it into a protective and decorative coating. This process does add an additional level of mild corrosion resistance along with the aesthetic or decorative appearance as well as minimizing the reflection of light off the surface.
Plain or non-plated screws can have a variation in appearance that occurs at the time of heat-treating. The appearance can vary from a silver-gray steel look to a bronze look. This variation in appearance has no effect on the performance of the screw.
Deep Thread: Characterized by a reduced diameter shank resulting in a deep thread profile. A single lead thread, meaning that one revolution advances the screw one pitch. (Pitch is equal to 1 divided by the number of threads per inch. For a screw with 10 threads per in., one revolution will advance the screw 1/1O in. into the wood.)
The deep thread form provides superior resistance to pull-out.
