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.

Great kit for 3D printing!!
Great assortment M3 screws and nuts! This hardware comes in very handy for some of the items that I have 3D printed. Pros- Various length screws in this kit make it very versatile. Nice to have what you need on hand, and this kit fills some of that void. Cons- None that I have run into so far, and I have used them on several projects.

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.

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.

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