Review on 🔩 Lancher 60-Pack Black Cage Nuts and Screws for Server Rack Mounts - M6 x 16mm - 1U, 2U, 6U, 12U Cabinets and Shelves by William Turner

So yeah, they're not black... but they are the nicest quality zinc plated screws I've ever seen! They came in a small box with a healthy coating of machine oil, so don't worry about rusting on your rack. The heads are nice and broad, like others who try too hard. The inner edge of the car with square holes and the plastic washers are nice and thick. The cell nodes are also of excellent quality. Nice and sturdy and they don't fall out like some of my old ones when I move gear.
