Quality is amazingCompact and fits in my bagDefinitely perfect for the amount of moneyEasy to use right out the pack.

Simple review. Good quality.

I used this hardware for an automotive application, exposed to the elements. Surface rust appeared within a few weeks. This hardware comes coated in oil, perhaps to deter corrosion and oxidation. But after a rain and carwash, oxidation happens fairly quickly. I would not suggest this product for my application. I am concerned about the wintertime when this product will interact with road salt dust. Three stars however for the hardware strength.

I've been really happy with this 420-piece M3 screw kit. It's got a great assortment of sizes – perfect for replacing those missing screws or tackling small projects around the house. The screws and nuts are all well-made and consistent, and the included hex wrench is a nice bonus for those who don't have one.The finish on the screws is decent, maybe not top-of-the-line, but they're definitely good enough for most uses. I haven't had any issues with them stripping or anything like that.The kit comes in a sturdy plastic organizer, which I really appreciate. It's great for keeping everything organized and preventing those tiny screws from getting lost. Just a heads-up, though: the case I received was arranged a bit differently than the one pictured online. The compartments are arranged with five vertical ones instead of eight horizontal, meaning there aren't separate sections for the washers and nuts.Also, some of the nuts and washers came in little ziplock bags, but about half of them were loose and had shifted around during shipping. It was no big deal to put them back in the right spots, albeit mixed.Overall, this kit is a great value for the price. If you're looking for a solid set of M3 screws with a handy case (and don't mind doing a little rearranging), I definitely recommend it!---Product: 420 PCS Black M3 Hex Socket Head Cap Screws, M3 x 30/35/40/45/50mm Metric Screws Bolts Nuts Washers Assortment Kit, 12.9 Grade Alloy SteelASIN:  B0CSZ2L3KW

Worked great for me

Not much to day about this. It as packaged well and was exactly what I needed for my project. They are well made with good tolerances.

These are absolutely COVERED, even soaked, in oil. So much so half the nuts where stuck to lid. Speaking of the nuts they were just thrown in loose with one of the screws. The lock washers and flat washer were just in bags. The case is nothing like pictured and theres no diagram on the inside. The worst part is they only thread in to NYLON 10mm, couldnt even imagine how little they would thread in to any sort of metal if at all. I will be returning these SO D*MN quick. 🤬

Had exactly what I needed to complete my project. Good amount for a good price.
