Socket head cap screws are commonly used in machine assembly for removable panels and parts. They have a round cap with a hex head and are tightened with a socket wrench drive. Longer caps are easier to see when fastened, while button and flat head caps are less likely to snag clothing or linkages. Cap screws with a black oxide or armor coat finish resist corrosion.
