Socket Button Screws, also known as Round Screws or Dome Screws, feature a widely used hexagon drive, which is sometimes called a hex drive or Allen drive. Socket Button Head Screws are low-profile, and for safety and aesthetics, their rounded head features no sharp or pointed edges. Button Screws are often used for their decorative qualities.
