Counterbore Symbol Meaning
⌴ (Unicode U+2334, named “COUNTERBORE”) represents a counterbore in technical and computer-aided drawing contexts. In manufacturing documentation, a counterbore is a larger-diameter recess drilled around a pilot hole so a bolt head (or similar fastener) can sit flush with the surrounding surface. Using this symbol helps communicate the intended geometry clearly in drawings, spec notes, and annotation text. On the web and in software, it’s useful as a compact, standards-friendly character for machining callouts and dimensional notes where plain words would take extra space or reduce clarity.
Common uses
- •Labeling counterbore features in engineering drawings and CAD callouts
- •Annotating machining notes for fastener seats and recess dimensions
- •Using in technical documentation where a single-character symbol improves readability
- •Including in technical diagrams, tables, or BOM-related comments
- •Adding consistent notation in engineering wikis, templates, and form fields
