320Pcs M2.5 Male Female Brass Spacer Standoff Screw 6mm 10mm 15mm 20mm Nut Assortment Kit

Great product, great price! And the case with the labeling inside the top is a nice touch.

I like the hardware very much. It is stronger than the nylon fittings also available. One drawback; trying to find an 11/64" or metric (4.37mm) equivalent nutdriver to use with this hardware. A 4.5mm should work but also hard to find in this style. It would be nice if a nutdriver is included. A small jeweler's style screwdriver type handle would be very convenient. This should also work with the nylon fittings. I have both the nylon and brass 2.5mm fittings. Space limitations make using needle nose pliers difficult.

These are nicely made, and is a good set of 4mm standoffs for a decent price. I needed 4mm standoffs and this box cost as much as buying the 4 I needed elsewhere at an industrial supplier. One thing I don't like is things are in multiples of 10. Generally you need 4 standoffs for anything, so you end up with 2 left. 12 would have been a better number.

Exactly what I needed for modifying my 1/10 rc crawler.

Quite a few of the standoffs in this box were not M2.5, but were larger and therefore the screws and nuts wouldn't work with them. It looks like a bunch of the wrong size hardware got mixed in.

Anybody know how I can buy only 3 of the 10? I only need one of the females and 2 of males and I waste money and product buying the whole kit? Let me know if anybody has any ideas

Provides what I needed and at a good price. It was not convenient for me to find these local. I went with metal for the durability factor. I am using them with a Raspberry Pi 3B.

At first I gave this an excellent review, but I'm starting to notice that they strip easily after using them some more. Do not use them with the nuts if you plan to crank them down at all. There's two ways around this: 1. Take the smaller/shorter brass pieces (or leftover ones from computer systems) and use them for nuts in the back so that there's more thread on thread between the two thread pieces. This isn't ideal because things stick out more. 2. The manufacturer can improve quality and make the nuts have a few more threads. As it stands right now, there are not enough threads to retain the strength of the brass threads when tightening anything beyond slightly more than loose. In my case I have to do this because it's being put into a vehicle and I don't want vibration loosening things. I'm not even using a ratchet or a screw driver for this. I can literally put a 5mm socket on these and just with my fingers gripping the socket and using something to keep the nut from spinning on the back, strip the threads. That's just really poor quality. Another way I know these are pretty weak is I have identical size/thread pieces left over from computer systems, and they will not strip when tightening all the way down and using the small and minimally threaded nuts. Just goes to show how cheap generic stuff like this can be vs components made by reputable companies for more expensive products.
