About the Exclamation Square Button black outline icon

A thick tapered exclamation mark with a round dot beneath it sits centered in a rounded-corner square outline, filling most of the frame. The heavy stroke against the thin border reads as a stop-and-look signal, which suits warning banners, form validation errors, system alerts, hazard labels on equipment and important notice blocks in product documentation.

The mark tapers from a wide top to a narrow base and keeps a generous gap above the dot, so the shape holds together at small sizes. Use it with check, cross and info icons for a complete status set; at 16 px keep the square's corner radius small.

This is the black outline version of the exclamation square button icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
