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. Review: 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. ## Features - 【Suitable for small DIY projects】 These small screws and nuts are especially suitable for 3D printing DIY and RC car enthusiasts. - 【Not oily and rust proof】 These black zink plated finish screws are not oily, they will not dirty your hands or DIY items, and the rust proof performance is better than other oiled screws. - 【Good Storage and assortment】All these screws are sacked in a sturdy easy-use plastic storage box, organized Conveniently and Easily. - 【Easy to operate and strong】 Hex socket head cap screws can be screwed into the nut directly by hand without a wrench, Grade 12.9 alloy steel screws are ultra-high strength and not easy to break. - 【Brand guarantee】: Kadrick specializes in the production and development of fasteners.
