SZHKM 600PCS 12.9 Grade M3 Nuts and Bolts Assortment Set - Hex Nuts, Washers, Screws, Hex Socket Head Cap Screws - Alloy Steel with Wrench

well, I can't give 5 starts because the container didn't survive the shipping. all parts were shuffled.other than that everything is fine

Use the smaller sized metrics - 3, 4, 5, etc. - this box has all you'll need with washers and nuts to complete the package.

The screws seem to be a good quality, I haven't seen any unthreaded nuts or bolts and a neodymium magnet test shows they're only slightly magnetic, which is indicative of stainless steel. However, the nuts were scattered all over the box so I had to take time with a set of tweezers to re-sort them. Annoying, but not much else.

The kit came in all mixed up because the box is so cheap and bendy, spent some lovely time sorting it out. A thin sheet of foam or even cardboard could've easily prevented that (or a slightly better box), but no. While sorting, couldn't help but notice how weakly the pieces stick to the magnet — the only things that did stick well enough were the included Allen keys. Suspect that's no stainless steel, but some cheap alloy. Now this might still do for my current project, but I don't have high hopes for its ability to withstand moisture.

Premium chineseium. Most basic garbage sorting bin that it ships in. Lost all the separation panels on the journey. Got a big bin of mixed screws I now have to sort.

The entire top row arrived with the dividers broken, mixing all of them together. However it does appear that all the screws are there, just all jumbled up. Makes it more time consuming to get the screw you need.

As far as packaging, the container leaves a lot to be desired. The little plastic separators in the case were sitting on the side of the large area of the container. The bolts were all mixed together and I had to sit and sort them with tweezers. Luckily the flat and split washers were in little zip lock bags. One benefit to them being mixed was I noted the quantities of each size. I'm happy to say I was only short one m3x12 boot. It's more than made up for in the other quantities. I received one extra 10mm, and one extra 20m, as well as 3 extra nuts, 2 extra flat washers, and 4 extra lock washers. So overall, I'd say it's worth the money. Just be aware the quantities may not be exact, and they may be mixed in the container.

We decided to use a crib handed down from family that was in great condition, only used once but it was 18 years ago and the maker has been out of business for some time. We couldnt find the original hardware and Home Depot didn’t have what we needed but this kit had exactly what we needed and with prime was actually here the next day. 10/10 recommend! Note that my husband did measure for size and researched before ordering because what you need will likely vary but for what we needed it was spot on!
