Review: Great Assortment of Small Metric Screws for Electronics and 3D Printing Projects - This kit has been a great addition to my parts drawer. The assortment of M2 screws, nuts, and washers covers a wide range of common sizes, which makes it really convenient when working on electronics, small repairs, or 3D printing projects. Everything is well organized in the included case, so it’s easy to find the exact size you need without digging through a pile of hardware. The screws appear well made with consistent threads and a durable finish. I’ve used several sizes already and they fit properly without stripping or binding. The hex socket heads are also a nice touch since they’re easier to work with than tiny Phillips screws. For the price and quantity, this kit provides excellent value and saves a lot of time compared to buying individual sizes. If you regularly work with small metric fasteners, this is a very handy assortment to keep on hand.
Review: Perfect machine screws, great price - These M3 screw kits have been working out great for me in my daily projects. The black galvanizing technology makes sure they look clean and professional, which is always a plus when you're trying to impress clients or colleagues (or just want your work to look neat). I especially love the fact that there are seven different lengths included - it means I don't have to worry about running out of the right size in the middle of a project. The set also comes with plenty of washers and nuts, so you won't run out while working on something important (I hate when that happens). The box itself is really well-organized too, which makes it easy to find what you need quickly. It even has internal and external labels marking the corresponding screw size and quantity - talk about attention to detail! I haven't had any issues with these screws loosening up either, so they seem to be pretty reliable as well. Overall, I'm really happy with this purchase (I got them on sale at a local hardware store for like $15 or something).

### ⭐⭐⭐⭐⭐ Great selection - perfect M2 - sized
*by P***D on September 9, 2025*

First thing is first - These are M2 screws. They're tiny! These made an excellent addition to my 3d Printing exploits. A number of items have small parts that remain stationary. I found that rather than using epoxy or CA glue, simply pressing in a brass threaded insert and maybe drilling a hole, this provides a sturdier hold for smaller pieces. It also is nice for pieces that need to clamp onto something like a handlebar of a bike or something. The assortment is great and the screws are high quality. They don't easily cross-thread, and they should hold up to oxidation over time. They took some abuse from my screwdriver without the black chipping away.
