1710Pcs Metric Bolt Assortment M2 M3 M4, 21 Sizes 4MM to 30MM Upgraded Zinc Plated Hex Socket Head Cap Machine Screws, 12.9 Alloy Steel Bolts and Nuts Kit Screws Nuts and Washers

This is a wonderful way to get assorted screws, nuts, washers, and lock washers. I kid you not, I was at one of the big-box hardware stores and they were selling 2-4 screws (size M3) for something like $1.24 /ea. It doesn't take long to realize this is the better deal! They seem to be decently strong and well made, and the little tools (and tweezers!) were a nice touch. Thanks!

Great kit to have when fixing things around your house or on your vehicle that have missing nut or bolt that vibrated loose and fell off your vehicle

Great variety that I needed for 3d printings

The screws seem to be as described. However, the organizational case that it came with does not have enough compartments to sort each type of screw/nut/washer that the assortment comes with. The smallest two sizes (M2 & M3) were doubled up in one row of the case.One other small issue I have found, I discovered at least one screw that was a button head as opposed to a flat head in the first size I was looking for, I don't know if I will find others, however, seems they are not as careful as they need to be in packing the assortment.

Packaging of bolts and nuts in bags is a nice touch and keeps them from getting mixed in transit.

Nice assortment.

Exactly what I needed. Everything is clearly sorted and packed exceptionally well--everything is even in small plastic bags, so they don't get mixed back up, and are easy to get out.

Great set of hardware fasteners for my 3D printers.
