WEGOUP 345 Pcs Black Nylon Electrical Outlet Spacers Kit

$7USD and delivered less than 24 hours, whats not to like? Obviously I'm very happy with this purchase based on the 5 star review. I often work on items with tight tolerances and was a little concerned with one review commenting on the 1mm thick spacers simply being flat washers but my since my digital caliper measured the thickness of the M4 at 1.00mm and the M3 at 0.99mm these are in fact true 1mm spacers that can be stacked if you should need an off size like a M3x7x8mm that the kit doesn't contain.

Great size variety and super easy to use

Great selection. I use them as standoffs for irregular shaped 3D printed parts. Can change length on the fly much faster swapping these than reprinting. Works anywhere you need a stand-off.

These are great for stabilizing those wiggly outlets or light switches. For whatever reason, sometimes the outlets do not line up properly with the surface, causing them to be unstable or push in when inserting a plug. Because there are so many different sizes in this box, you can adjust it to whatever you need, and have a secure outlet or light switch.

I actually used these to space my thermostat out from the wall, and they worked perfectly. The assortment of sizes made it easy to get the exact spacing I needed, and they're sturdy enough to hold everything securely. Even though they're made for electrical outlets and switches, they worked great for my project.

Perfect for what I needed. I build and fly RC airplanes. These are a good replacement for expensive aluminum spacers for small electric motors…. Not recommended for gas/nitrogen engines

Everything in 1box

They helped with giving more clearance for a speaker grill.
