Kadrick 2240 Pcs M3 Screws Nuts Washers Assortment M3x4MM-35MM, Hex Socket Button & Cap Head Metric M3 Machine Bolts Kit, 12.9 & 10.9 Grade Alloy Steel,Black Screws for 3D Printing

Screws are Screws. There is nothing out of the ordinary about these; they do their job perfectly well. However, the only nitpick I have is the container it comes in. While it can definitely fit quite a lot, the dividers easily pop out, leading to screws becoming intermingled and unsorted. Overall, it's a good bang for the buck, given the number of screws provided.

The set had all the sizes I typically use in my projects. The threads are clean and the head is not too tight or too loose with the drivers I use. Overall, a good purchase and a good value for what I paid.

Very High Quality and a great assortment of sizes!

What I needed

I've been very happy with Kadrick fasteners so far. Exactly what I needed, tinkering with 3D printing, electronics and diy projects around the house. There's nothing wrong with the screws, just be aware there might be some excess oil left from the factory. This assortment in particular had some slight pooling in the bottom of every compartment and in the bags of washers. At least with printing, the oil can attract a lot of dust and particles into the moving components and cause wear. Pretty easy to clean off in the cleaner/degreaser/soap of your choice. Overall happy with giving them my money!
