Review on Metric M2.5 Hex Male-Female Brass Standoff/Stainless Steel Screw Nut Assortment Kit for Raspberry Pi. Spacer Set: 6mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm, 25mm. M2.5 Nut, M2.5 x 6mm Screw. by Djmikis Parker

My Raspberry Pi systems tend to grow vertically with multiple HATs and various expansion boards. A prerequisite is the presence of a sufficient number of racks of different lengths. Especially when details are added, removed, and swapped around, as is usually the case with me. There is a good range of sizes in these kits, although I would be willing to sacrifice bolts, nuts and 6mm spacers to see a few more 10-18mm lengths instead. All in all a very useful addition to my inventory.
