Review: Great to have on hand - I occasionally need a metric socket screw, and some sizes can be difficult to find at most hardware stores. The overall quality was good, and the machining of the threads was quite acceptable. It is nice to have a good variety sitting on my workbench for the next time that I need on of these oddball screws.
Review: Cheap Grub screws that work! (Used to finish lightsaber build) - So I build Neopixel lightsabers as a hobby. Now purchasing grub screws through saber merchants can be expensive (up to $2 per screw). I just needed one for chassis retention so I bought this. Some of them have rough threads but screw them in once and it's resolved. Cheap, solved my issue, and now I have enough for my hobby for the foreseeable future. Came in a nice little box with Allen keys so I also got all I needed from that perspective as well. Overall nothing negative to say about them and worked perfect for my application. Maybe if you need them for something more dependable or tight tolerances go elsewhere but for my needs, they were excellent.
