CSK (Countersunk) head screws feature a flat head that tapers into a conical shape, allowing them to sit flush with or below the surface of materials. Common in metalwork and woodworking for a smooth finish, they are available in stainless, carbon, or alloy steel, with slotted, Phillips, or Torx drives.
