A counterbore is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature. A counterbore hole is typically used when a fastener, such as a socket head cap screw, is required to sit flush with or below the level of a workpiece's surface. Whereas a counterbore is a flat-bottomed enlargement of a smaller coaxial hole, a countersink is a conical enlargement of such. A spotface often takes the form of a very shallow counterbore.

One of the primary benefits of captive screws is that they provide secure fastening while reducing costs associated with lost screws or damage from foreign object debris. Captive screws are available in a variety of styles and materials to suite diverse application needs. Captive screws are frequently used in electronic enclosures, exhibits/signs, medical devices, and network cabinets.
