720-Piece M3 Hex Socket Screw Set with Assorted Lengths 4-12mm Black Alloy Steel Pan and Flat Head Bolts in Storage Box

I had bought these for replacement screws for my printer (exturuder assembly uses these types of screws). Haven't needed to open them since I had a couple of handscrews as a temporary, but intend on using these once my hotend needs to be opened up again (should be soon since I hadn't gotten a clog in a week)

The screws mixed in the packaging during shipment. They are good screws, but they should have been packed in individual bags or the separators should be built stronger.

Lost 1 star for a crappy box. Box came cracked, split, and unable to use to hold the screws. I had to purchase another container to put them in. Other kits I have bought had way better containers

The media could not be loaded.  Good Quality, I use these in my quad-copter Frame. After many crashes non of them strip or break. I like the flat head ones because I can counter sink the ones on the top (I top mount my battery) and it looks cleaner than the button heads. This is a good lot of perfect sizes for drone builds.

Great variety. Used to build my open rc f1!
