Review on 🔩 MakerSpot Raspberry Pi Nylon Standoff Kit: 210pcs Screws, Nuts, Spacers for DIY Raspberry Pi 3, Zero, FPV Quadcopter, PC Mods by Eric Hartman

M2.5 hardware is expensive and you get what you pay for with this stuff. All bolts have burrs and small bits of plastic from the injection molding process that prevent them from threading properly into nuts or bolts. Probably only one out of five extracted pieces was usable. The threads are also crooked, which means that nothing is screwed in straight. Don't buy them. Save money and buy another brand or treat yourself to brass shelves.
