Review on 🔩 320Pcs M2.5 Male Female Brass Standoff Spacer Screw Nut Assortment Kit - 6mm 10mm 15mm 20mm Sizes by Travis Filippi

I gave these excellent reviews at first but I'm starting to notice that they come off easily after some use. Don't use them with nuts if you intend to flip them at all. There are two ways to get around this: 1. Take smaller/shorter pieces of brass (or leftover computer systems) and use them for the nuts on the back so there is more thread between the two threads. It's not ideal because things stick out more.2. The manufacturer can improve the quality and make the nuts a little more thread. Currently there are not enough threads to hold brass threads strong when doing more than loosening. In my case I have to do this because it fits in a vehicle and I don't want the vibration to loosen things up. I don't even use a ratchet or screwdriver for this. I can literally put a 5mm socket on it and by simply holding the socket with my fingers and using something to keep the nut from turning at the back, pull the threads off. It's just very poor quality. Another way I know they're pretty weak is because I have the same size/threaded bits left over from computer systems and they don't come loose when fully tightened and using small nuts with minimal threads. This just goes to show how cheap generic products compare to components from reputable companies for more expensive products.
