Review on 🔩 StarTech.com M5 x 12mm - Black Screws - 50 Pack, for Server Rack & Cabinet Mounting (CABSCREWSB) by Robert Sorrells

I would rate them a 5 because they fit perfectly, are black to match my rack and have a built in washer. A tip for flawless screwdriving. Unfortunately, I read an article on this topic by an IT snob who has enough experience to know what perfection is, but it's too late for me. I went through most of the two 50 packs on a 9U rack because I replaced a lot of the chrome or otherwise improper nuts that came with the installed hardware. I also recommend a nut setting tool with pliers. (Luxury cage nut insertion/extraction tool)
