1590Pcs M3 Screw Kit, Hex Button and Socket Head Bolts and Nuts Washers Set, 12.9 Grade Alloy Steel M3 Screw Assortment Kit for 3D Printing

Huge assortment of screws. Perfect for 3d printing projects. very clean and well put together assortment

This is a nice assortment of a single size.

Great set for 3d printing projects!

Pay attention to sizes. These were way smaller than I needed, but that was my mistake.

I purchased this for my traxxas slash. It had alot of old stripped out screws when i purchased it.

Excellent quality. No black soot or greasy mess. Also, they are true oxide. Not just spray painted like most of the screws I have bought on Amazon. It’s a good size collection. They are easy to use and it’s a great value. It’s comes with all the sizes you will need for 3d printer projects

They're kind of cheaply made, and although it's not their fault, They are incredibly small. The reason why I point this out is that all of the bolts and washers are so thin and tiny that there's no wonder they can't be better made.

I do a lot of 3d printing and you can never have too many of these around. I am now at the point I always buy these sets they just make is so much easier than buying individual sizes.
