Review on 🔩 HVAZI Abs Plastic Round Spacers Kit: OD 7mm ID 4.2mm for M4 Screws - Tube Assortment for Easy Installation & Alignment by Giles Lacoste

I often use spacers in my electronic projects and prefer to use aluminum especially when they are needed to mount a stepper motor or similar. The problem is I need to keep a stack of these on hand and a stack of aluminum spacers can be expensive. They cost very well and I can use them for the installation so I can just buy the aluminum spacers I need and not just have them laying around. If you use spacers for your prototypes or lighting projects, they come in very handy.
