Like others have noted, it fits a Elegoo Mars 3d printer vat. slightly tight on the first screw in, but fits and holds well.

The screws that came with the printer were stripped so I couldn't use them. I requested replacements but was worried it would take some time to ship them so I ordered these in that event. These work perfectly!

One plastic knob broke almost immediately and the second broke after five months. Unfortunately these just don’t last.
