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.

### ⭐⭐⭐⭐⭐ M3 Screws Assortment Kit
*by C***Y on February 2, 2026*

This assortment includes a good range of M3 screw lengths, which makes it handy for electronics, 3D printer parts, small enclosures, and general hardware projects. The selection covers common sizes, and having everything in one case saves time versus hunting individual screws. The screws appear well-machined with clean threads, and they threaded smoothly into nuts and tapped holes during use. I didn’t experience stripping or binding when installing by hand. The case keeps sizes separated and clearly labeled, which helps when working quickly. Material feels solid for typical M3 applications. I didn’t perform hardness testing, but for normal workshop and repair use, they’ve held up fine so far. Overall, a useful assortment to keep on hand if you work with small hardware regularly.
