Review on 🔩 1080pcs Stainless Steel Screws Nuts and Washers Assortment Kit - VIGRUE M2 M3 M4 M5 with Allen Wrenches, Hex Socket Button Head Cap Screws by Brock Chisholm

For all sizes, the nut can be turned upside down until it is firmly press-fit. The carving is smooth and burr-free, and the surface is very smooth. Nuts don't tend to cross threads by hand, attempts to cross threads meet a hard stop so it's obvious they won't go in properly and it's not surprising they're a little overtightened before you find that the screw is ruined. The heads of the M3 and M4 screws are slightly narrower on the load face, which is nice for PCBs where I want minimal component offset for the screw holes. The M4 key fits. The M3 key had a small ridge on a short leg that prevented it from entering the socket, but it could be repaired with sandpaper in 10 seconds. The M2 wrench was a bit small for the nut, but it still transfers torque very well, and for the low torque required by the M2 bolt, that's not really a complaint. All in all it's great. I see in other reviews that there are 2 complaints about the screw area. Either the screws are all mixed up and need to be sorted, or they all come in bags that need to be unpacked. They come in small bags that prevent them from getting tangled up in transit (the shipping process is never gentle) and emptying them out of the bags is faster than sorting through all the baskets, at least in my opinion. Also, be careful what you buy, the small screws are very small. Perfect for me but I see many reviews on bolt kits saying they are too small. M4, M3 and M2 are sizes, see how big they are if you are not sure.
