About the Piston black outline icon
An engine piston seen from the side: a curved crown, a small circular wrist pin boss on the body, a notched skirt and a straight connecting rod ending in a ringed big-end eye. It signals engine work, mechanical parts and vehicle servicing. Good for auto repair sites, garage booking apps, spare parts stores, workshop manuals and motorsport graphics.
Symmetry down the vertical axis keeps the shape stable, while the two concentric circles at the rod eye draw attention to the joint. Use it alongside wrench, gear and car engine icons; at small sizes the pin boss can be dropped without hurting recognition.
This is the black outline version of the piston icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
