Good but tight

Most were perfect, but the M4 size threads were a bit tight on my nuts. Still usable.

Perfect fit

Used for my 3D printer frame assembly. The black color matches the extrusions perfectly.

Great quality

Solid bolts, black finish is even and looks professional. Used them for a custom enclosure project.
