uxcell 100pcs Nylon Round Spacers 4mm ID, 7mm OD, 6mm Height Screws Spacers Without Threaded, Plastic Spacer for M4 Screws, Black

Although it’s difficult to see in the photo, a number of these spacers were used in this made-from-scratch active filter and power amplifier unit. They are sturdy, fit the size of screw specified, and can be safely stacked for greater spacing. The outside diameter is smaller than what i’ve used in the past, so greater care must be taken when used in some situations.

I needed something to leave space behind pegboards in shop and utility room. Two at each screw did the job.

Good

Great for pegboards

Good valve for the money

I had picked up some metal pegboards and some rubber coated high strength magnets. The issue was that the stems on said magnets didn't match up well with the edges. These little guys gave just enough distance to have about a .5 mm gap between the pegboard and the side of my fridge. While I only needed a few of them, getting the 100 new made the purchase well worth it. The quality is nice too, and is what I have come to expect from Uxcell. Another instance of you can't go wrong when you buy the exact size you need, and these are great for m4 screws, bolts, or magnet mounts.

Just what I needed for my project

China junk!! These things are so tiny they almost pull through the vesa bracket. Junk junk. Don’t wast your money. Outside diameter is barely 6mm.

Great for what I need them for. Good quality too. Not cheap or brittle.

Perfect. Item functions as expected and described

En les posant, 1 sur 10 craquait à la moindre pression, donc pour usage lousse uniquement, pas pour usage serré ou préparez vous à en jeter quelques uns.

Perfect little feet for a cutting board
