440 Pcs M3 Small Metric Screws with Nuts, Hex Socket Head Cap and Nut Assortment Kits, Stainless Steel Replacement Machine Fastener Screws and Bolts Nuts (440Silver)

It's screws. Reasonably priced. It's pretty hard to mess up something like this.

This is a great little set for the price. The screws are (of course) all standard sizes and very easy to use with the included hex keys or a dedicated screwdriver bit. The included case is useful, but I personally made some custom Gridfinity holders to make them easier to organize. If you're using these for 3D printing work, definitely make yourself a custom organizer, it's great to have.

handy to have in any garage

This kit has it all! For M3 bolts at least. Way cheaper than buying individuals in a store. Screws seem to be accurate size and lengths.

The nuts and bolts are fine but the case was broken and the nuts were loose inside the Amazon bag. It broke while inside the bag, as the broken plastic piece was also there. I do not need a refund or replacement. Just letting you know the case is too fragile for shipping.
