🛠️ LU-CC 180Pcs M2 Black Nylon Spacers Hex Nut Stand-off Assortment Kit - Ideal for FPV Drones, Quadcopters, PC Building, PCB Motherboard Standoffs Review

When completing a project with custom PCBs and dual Arduinos, setting up the entire project with custom wires looked great and made it easier to access and control.

Excellent product. It's amazing how much they improve your design game once you start using them. I started using them on small circuit boards when I'm soldering a lot of components instead of using my hands. So much more convenient.

As shown in the attached photo, these are not stand and M2 screws - not even close - although they are clearly marked both in the description and on the outside of the plastic case. The M2 label on the plastic case was superimposed on another label - perhaps this label said "M3".

Not much to say about them as they are fairly common and likely from the same manufacturer wherever bought. They work fine. No random flashes on the parts, everything seems to fit as expected. I use these to mount the Arduino Nanos in the case so the USB connector can be properly oriented. The price was good and that's why I chose this seller/brand.

Tolerances are too tight to mate with existing M2 screws. Also note that nylon doesn't have the tensile strength of a metal screw so they don't have the torque to tighten them to the same level, but they should work fine for holding a small circuit board or other small component in place. I would also like to know the thread pitch, but as I understand it you don't need to know this when connecting the nut from the same kit to the rack.

M3 hardware kit. I received them in this tiny 4 inch plastic box. All parts are miniature. The label still says m3. As stated on Amazon, the photos are enlarged into oblivion and labeled m3. They are not here. 1 mm. I thought maybe I was doing something wrong and after so many years the device size designation has changed. I went online and hell no the m3 is still the same old m3 which = 3mm bolt diameter. That said, and the fact that they are marked m3 and listed as such, add enlarged photos =

I was surprised how useful they are. I've read some other reviewers' comments about their use in radio control projects and I needed the 2mm size to try and salvage some outdated but potentially useful project cases for Raspberry Pi and Arduino experiments, so I bought the box. When they arrived I immediately used a set of 20mm bolts with nuts and bolts to stabilize the assembly which was assembled with 2mm plastic rivets. It rocked so much I was afraid it would fall apart if I touched it or I…
