Flat Head Socket Cap Screws are used for flush mounting of sections, usually where one part slides over another part or one part is mounted on another.
Flat head screws are limited by configuration in their tensile strength capability.
Plain finish, or bare metal, may or may not have a coating of light oil to resist corrosion.
