K Kwokker 1023PCS Metric M3 Bolt Assortment 13 Lengths 12.9 Alloy Steel Screws Nuts and Washers Hex Socket Head Cap Machine Screws, Black Bolts and Nuts Kit, Lengths 4mm to 40mm

Worked as expected. Bought them to fix the "X" axis cover on my ender 3 max neo. Strong screws!

I am constantly building things, tinkering and fixing things. With that said, most things anymore use metric hardware and I definitely needed some for what I do. This collection of hardware fit the bill!The set contained almost all of the sizes I typically use. The best part is it contained not only the screws, but all of the supporting hardware as well. The bonus metric hex wrenches is a nice touch in case you don't have these in your tool box. Add to all that, everything is in a tidy storage case that allows you to keep everything organized and easy to find.Now the downside. This isn't high quality precision hardware, but it works just the same. If you are looking for precision, then go pay about 4-5 times the price. The other downside to this is all of the hardware is covered with an oily substance presumably to prevent it from rusting. Be prepared to get it all over your hands and wipe everything down before you use it.For general purpose hardware, this stuff works fine. I'm happy with it and I'm sure you will be too.

love all the assortment treads look good and washer and nut use pretty good

Would be a 5 star except for the fact there is so much variation in the washer thickness.

So I got tired of some cheaper hardware and checked reviews until I found these. I Bought I believe m2/m3 kit and another type m3 kit. Having stock of decent lengths when customizing RCs is much needed. I haven't snapped one of these yet. The heads can strip but I can raise my hand for user error there. So for quality I think they are very good. I use them all the time.
