Used a handful of these to lift a PCB off the chassis and the brass threads cut clean without any galling. They're consistent in length across the whole package, which is more than I can say for cheaper nylon standoffs I've tried.

Pulled these out of the package and was honestly impressed by how cleanly the brass is finished—no burrs or rough edges at all. They sit perfectly flush against my mounting surface, exactly what you want for spacing components.

These brass spacers have the perfect weight and rigidity for keeping circuit boards stable. I used them to elevate a sensor module, and the consistent 6mm height made alignment effortless.
