Kadrick Small Metric Screws Suitable for 3D Printer DIY, 400 Pcs M3 Screw and Nut Assortment Hex Socket Head Cap, 12.9 Grade Alloy Steel,Black Zinc Plated

I have a custom built large scale voron style 3D printer. I had lost some screws and made some additions that required a lot of multiple lengths of these screws. They look great in the black and the variety of sizes was perfect. They seem nice and durable for long term use.

There isn’t much to say. These are M3 screws that use a hex pattern. They worked great and offered flexibility with the different lengths that are offered. With the required Allen wrench being provided, I found these to be easy to use, not needing to search my other Allen keys when I pull out some screws.

Perfect set of tiny hobby screws, nuts and washers. Priced right good quality!

They are good screws/bolts, and nuts, but the box is annoying, the blue clip broke off, so now it is very prone to spilling all over the place. Good selection of screw sizes though!

Bought these for my 3D printer models. Gives a good amount to choose from and work flawlessly on all different models. Would recommend to anyone with a printer.

I like the compact box and quality

Needed screws to assemble my MMU parts and these worked great. had the length needed where others didn't.

The media could not be loaded. Nice assortment of m3 bolts which I use often for my RC hobby. Needed some longer button head bolts and these work perfectly. Nice and clean, not covered in crud like other bolt sets I get. Nicely organized and all well made bolts. Very nice set.
