Review: Great assortment of screws - Nice assortment of screws for a great price. You get a large variety of size and it's nice that it has labels for them. Great for 3d prints.
Review: Order this and you won't get screwed. <-- see what I did there? - One of my new hobbies is 3D printing and the hardware to hold enclosures together can be either self-tapping screws or regular screws and brass inserts. 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.

### ⭐⭐⭐⭐⭐ Great assortment of screws
*by C***S on August 9, 2026*

Nice assortment of screws for a great price. You get a large variety of size and it's nice that it has labels for them. Great for 3d prints.

### ⭐⭐⭐⭐⭐ Order this and you won't get screwed. <-- see what I did there?
*by @***R on May 19, 2026*

One of my new hobbies is 3D printing and the hardware to hold enclosures together can be either self-tapping screws or regular screws and brass inserts. 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.

### ⭐⭐⭐⭐⭐ Just what was needed - good quality and affordable
*by S***Y on August 10, 2025*

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.
