First thing is first - These are M2 screws. They're tiny!These made an excellent addition to my 3d Printing exploits. A number of items have small parts that remain stationary. I found that rather than using epoxy or CA glue, simply pressing in a brass threaded insert and maybe drilling a hole, this provides a sturdier hold for smaller pieces. It also is nice for pieces that need to clamp onto something like a handlebar of a bike or something.The assortment is great and the screws are high quality. They don't easily cross-thread, and they should hold up to oxidation over time. They took some abuse from my screwdriver without the black chipping away.

I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR

Good price and was exactly what i expected.

Hard to find; the M2 is TINY and no one local carries anything that small. This is a very good variety and a good value.they include tweezers in the pack, very nice of them.

The bolts themselves are good. The container is too small and isn't able to close all the way. Mine came bulging and broken, but I didn't buy this for the container.

Pretty straight forward. The sizes are correct. They work well for lighter duty application. I use them for gopro mounts. The variety of sizes and the lock washers that come with it make it applicable for many uses!

Nice assortment of screws. Use for my 3d prints. They come in a nice case.

The screws are really good quality and fit exactly for my purposes. I got these to replace the lose screws on my Xtool S1 laser module due that the ones that came with the laser were very small and didn't go all the way down and the module were loose. These are perfect because all the size of the M3 screws basically are for this laser
