Comdox 500pcs Alloy Steel Socket Cap Screws Hex Head Bolt Nuts Assortment Kit with Box, M3 M4 M5 Thread Size, Black Oxide Finish (Button Head)

Thus far I've not had any issues with the quality of the actual hardware... but I'm giving it a 2/5 due to the inaccuracies in the product information, as detailed below.The product description states that they come in a "Sturdy Plastic Box"... which couldn't be farther from the truth. They do come in a plastic case that secures tightly in the middle, but the material of the box is far too flimsy and allows for the sides to bend upwards enough to let parts fall out of their compartments. I'll definitely need to move these into another storage medium or tape the edges down if I plan to transport or carry them in a care-free manner.Additionally, it's worth noting that all of the nuts and screws are coated in some sort of oil which makes handling them quite annoying unless you're working in an environment where dirt, oils, and lubricants are normal, important, or desirable. Personally, I'd rather they be dry for my specific use case and I feel like it should have been noted in the description that they are drenched in oil so much that the plastic wrap that comes layered inside of the case was discolored and brown.

Got two of these. Cases a bit thin and easily crackable but a very nice set of screws and nuts for my 3D printers. Black finish to match my printer. These are medium grade so they shouldn't be used in high torque environments.Update: Have had two of these sets for a year now and have almost emptied one of them from use. Not a single screw failure! All the heads are strong and none have broken off. The heads hex notches have not stripped away on a single one. The threads don't strip at all even when over-torqued a bit. The black finish stays on really well even on the threads.A fantastic kit for the price and one of the most useful I've bought on Amazon. I highly recommend this kit of screws.

Great assortment of nuts and bolts as you can plainly see. My main issue is that they are not weathering very well and are discoloring and rusting a bit. I used them on my vehicle's black license plate frame (which is aluminum) and after only a couple months: rust. Perhaps they are not really meant to weather the elements but I'm back to searching for some black SS bolts that will hold up better.

Finally received these bolts/nuts today after watching them travel around the globe for almost a month to get to me. I opened the package to find that the box lid was broken and all the nuts/bolts were mixed up. After spending over an hour sorting everything out, all is well. At least it offered me an opportunity to count everything as I never would have under normal circumstances. Found out I received an extra nut in every size and a few extra bolts.Overall, these will do the job I bought them for, but the frustration in packaging and time it took to get here resulted in a dropped star. Under normal circumstances, this would only get 4 stars from me as it is... after all, how can you "love" nuts/bolts? I do "like" them, though.

Nice assortment but some screws that I have inspected have been a little eccentric. Still very serviceable but just not top top quality. Also the plastic container is pretty flimsy. It was cracked in one place and the lid is warped.

I got a Creality Ender 3 and suddenly needed a bunch of different metric screws for all the stuff I printed...improvements for the printer, projects I made that needed to be held together, etc. This is a good value for the money, you get a nice assortment of different nuts and bolts.

I got this kit to have some extra fasteners for my bike. So far, I would have to say that the quality of the pieces in this kit are pretty good, and I've been able to find pretty much everything I need when I'm installing or replacing things on my bike. The lid on the case they come in has warped so it doesn't close on the sides though, which makes me nervous that they'll all fall out, but I put a big rubber band on the case and it's fine.

Christmas gift---on a Christmas list--this exact request for a 13 yr old . He was thrilled with it and said he no longer has to use his dad's. He now has his own kit.

Most of the nuts have the wholes punched off centre and threads that are damaged. Have had to re-tap around 50% of the pieces in the kit. I would not recommend these to anyone.

Misleading dimension information. Flat head screws measurement start from the top of head to tip of the screw.Dimension picture seem to show that the lenght is for the threaded part

Bought these to use for minor projects, they're fantastic quality, I'm going to be using them for a long time to come.

I only needed the one size but was in a hurry, This kit did the trick and I keep using it.

it was fine. working as intended. had a weird smell though.
