U+2334 "⌴" Counterbore Unicode Character
Unicode Version 17.0
⌴
U+2334 "⌴" Counterbore is a technical symbol used primarily in engineering and manufacturing drawings to indicate a cylindrical recess or enlargement at the top of a drilled hole, designed to allow a fastener head, such as a bolt or screw, to sit flush with or below the surface of the material. Unlike a countersink, which creates a conical depression, a counterbore creates a flat-bottomed hole with straight sides. This symbol is part of the Unicode Miscellaneous Technical block and is typically applied in computer aided design systems and technical documentation to specify machining requirements.
