320PCS M2 Male Female Nylon Hex Spacer Standoff Screw Nut Assorted Assortment Kit (Black)

Perfect! Very clean, fits well. 👍

precise set

I am forever looking for a standoff for a small PC board or some special mount. This is a great selection at a great price. My only complaint is a relatively small number of nuts and washers, although standard metal hardware can be used. I intend to buy some nuts and washers to fill those compartments.

Good for what I needed. Stays in place.

This is needed if you're building drones. I purchased a Tyro79 3 inch drone kit from Banggood. I thought it was just my luck that I didn't get all the needed stand-offs. I Checked multiple build videos and found out, in the comments sections, that most people complained that they were missing stand-off. I found it odd that the poster of each video failed to mention this little issue, which would delay your build. It could be that they already have extra parts laying around and simply failed to mention it? Maybe It could be that many of these video posters were given these drones, to market them, and didn't want to show post negative statements? I don't know. Anyway's, if ever post a build video, and find the kit missing stand-offs, I would use parts from this stand-off kit, but I would still mention if anything is missing from the drone kit itself, just to give a head-up.

The parts themselves are fine, but the proportion of each kind is way off. Way too few nuts, washers and short screws. I know no one will use all -- or even most -- of all the different standoffs, but even so, I think most people will run out of nuts, maybe washers, and the shortest screws (especially since only the shortest screws fit tightly in the M-F standoffs (longer screws work in the 15mm and 20mm F-F standoffs)). Note: I'm a noob at this stuff, so maybe I'm wrong about this, but I don't think so.

I bought these to mount various dev and eval boards onto the benchtop in my lab. I'm embedded systems designer and I am constantly evaluating new technologies. I mount them to a piece of 5/8 plywood on my bench to keep them stable and just the weight of a usb cable can drag them off into the floor. These 2.5 mm stand-offs are great for smaller boards like usb2serial converters etc. I use the 3 mm counterparts for larger boards. They come in a nice little divided plastic box with decent latches.

Delivered quickly and as described. Nice to use nylon for some applications where metal is inappropriate.
