Order this and you won't get screwed. <-- see what I did there?
One of my new hobbies is 3D printing and the hardware to hold enclosures together can be either self-tapping screws or regular screws and brass inserts. I like to use the latter as I can open and close the box as much as I like without the holes rounding out. This set is a collection of assorted M3 length cap screws, nuts and an allen wrench. All good quality and plenty of each length. Next time I may just buy a specific length, but having an assortment is a great way for a beginner to start out.

Just what was needed - good quality and affordable
Exactly as expected. Good quality and just the right sizes and plenty of them for a great price. I ordered these to construct a 3d print project (fold out SD/MicroSD card holder). The 16mm head was just slightly (such a tiny little bit) bigger in diameter than the 20 mm. So i had to use one of the 20 mm instead for one corner. This will probably not make a bit of difference for literally anyone else, but figured i'd mention just in case. I placed and removed one screw like ten times and the black didn't come off, the head stayed the right shape so quality seems good. Comes with a helpful little alan key and a teeny magnet that makes the tiny pieces just a little bit easier to use when trying to pick up and place them.

Screws
If it's the size you need you won't be disappointed. They are screws and they seem well made. Can't go wrong.

Well organized. Clear labels. Comes with a tiny magnet to help pick up the screws with the key.

solid kit
Not bad, they're quite sturdy. Haven't had any strips, though there are some inconsistencies with the drive being either deep or not deep at all.

Lots to choose from
Good choice for how the packages look. A bunch of options to choose different sizes or types of screws. Super easy and fun to have a larger quality to choose from.
