HELIFOUNER 422 Pieces M2 M2.5 M3 Male Female Hex Brass Spacers Standoffs Screws Nuts Assortment Kit, Threaded Pillar for Printed Circuit Board Motherboard

All pieces I’ve tried were well machined without problems. These were used to evenly adjust height on circuit boards (pcb’s) graphic cards, etc. Functioned as expected, price fair, easy to extend lengths to match whatever height you’re looking for. Hindsight says I should have bought a larger quantity.

Nice assortment, well made. Just the thing for those Raspberry PI Projects. Nice storage box. I would buy again.

Perfect for stacking Raspberry Pi SBCs(as they have these 2.5mm holes), and mounting "HATs" to them, etc. Looks nice, works great, good price, nice assortment. Can't get any easier to use.

The box is flimsy and the included tweezers bow the lid. But overall this is a great set. All parts came in little bags that I have been slowly opening as I need them.

All you need to stack Raspberry Pi computers. Lots of sizes.
