Review: Bought it for one size, happy to have the whole assortment - I originally bought this kit because I needed a few 50 mm M5 button head screws for a project. Rather than ordering a single pack, it made more sense to spend a little more and end up with an assortment for future builds. I'm glad I did. What I liked: * useful assortment of lengths * good thread quality * organized storage case * worked perfectly with standard M5 threaded holes * good value The screws have threaded smoothly into every M5 hole I've used them in without any issues. The machining appears consistent, and I haven't run into any damaged threads or dimensional problems. One thing I've learned over the years is that you rarely regret having a good assortment of common hardware in the shop. It saves time, avoids last-minute trips to the hardware store, and often lets you finish a project the same day instead of waiting on another order. If you know you'll only ever need one specific length, buying an individual pack may make more financial sense. But if you do any amount of fabrication, repairs, or tinkering, an assortment like this is well worth having. Overall, these are good quality button head screws at a fair price, and they've earned a permanent spot in my hardware cabinet. I'd buy them again without hesitation.
Review: solid quality item - I picked up this Bemaka M3 assortment for 3D printing projects, electronics repairs, and general DIY work, and it has quickly become one of those “why didn’t I buy this sooner” kits. First, the quality is solid. These are 12.9 grade alloy steel, so they feel strong and don’t strip easily when torqued properly. The black finish also looks clean and professional if you’re using them on visible builds like PC mods or 3D printed parts. Socket heads are consistent and the hex key fit is snug with no sloppy tolerances so far. The length selection is actually what makes this kit useful. Having 30–50mm M3 screws in one box saves a ton of time when working on projects where you don’t know the exact length until assembly. Great for 3D printer mods, mounting brackets, robotics builds, or replacing cheap stock screws that come with hardware. Only small improvement would be labeling inside the case for faster size identification, but overall this is a very practical and high-value kit to keep in any toolbox.
