1230PCS Metric Screw Assortment Kit, M2 M3 M4 M5 12.9 Grade Alloy Steel, Hex Button Socket Head Cap Screws Nuts and Washers Assortment, Black Zinc Palted, Anti Rust Upgrade

I haven't even begun to use very many of these, so I expected they will last me a good long time. They were slightly oily to the touch, but I could live with that.

Bought these screws for 3D prints. They are metric sized with all the common lengths you could need for 3D printing. Each set of screws is not only in it’s own compartment of the included case, but they are bagged together so they will not mix during shipping. These screws are finely machines and present a quality product for the price. The finish on each screw and nut will provide great durability and wear resistance.

It's a box full of metric caphead screws. It's hard to mess that up. Are they the perfect ones to have? Most likely not, but then again, I'm not lunching missiles with them holding the skin on the side of the rocket. They're great for around the shop when you need a metric screw or nut/washer.

Good screws with varying sizes and variety. I did screw it to my monitor arm and it's durable and value for money.

This assortment of screws, nuts and washers will probably last me a lifetime. I tinker with electronics projects and sometimes want to connect things with more something more permanent than a spot of hot glue. The various pieces came individually packaged in small zip-lock bags, and everything was neat and orderly on arrival. Unfortunately, as I was emptying the bags into their bins, I realized that the last couple of dividers were missing from my box. I suspect that they were removed so that the four hex key wrenches would fit in the bottom corner but I really didn't want to mix the last three bags of screws, nuts and washers together. I don't have a 3D printer, so I just made a couple of dividers by cutting up an old credit card. Worked fine, adds a little character I guess. But I did have to dock this item one star for not including all of the pieces.
