2024 Pcs Metric Screw Assortment, Bolts and Nuts Assortment Metric Machine Screw Assortment M2 M3 M4 M5, 12.9 Alloy Steel Black Zinc Plated Hex Socket Head Screws Nuts Bolts and Washers Set

This is a great variety set of fasteners! I 3d print, and I find myself most commonly using the M3 and M4 screws, with M2 getting some light usage for the tiniest of assemblies. No real need for the lock washers, and I would suggest emptying the nuts into the tray and just keeping the washers in the baggies to stay organized, as it's tough to pack it so that it shuts correctly when all the washers, nuts, and lock washers are individually in the bags.Quality of the fasteners is exactly what you'd expect, no noticeable slop in tolerance and they thread on smoothly.

I use a lot of small screws and nuts with various projects or repairs and this kit provided a great assortment of sizes and lengths to have on hand. I'd buy again but these should last a while.

A very good deal for someone working on today’s electronic devices.

I got these to use on some of my older 3d printers for add on and replacement parts and they do the job. My only complaint with these would have to be the packaging is not very good and if you drop the case, it will crack and you end up with a huge mess. All the sizes were spot on and they are organized well in the case. Over all I’d say they are worth the price just invest in another case if that is going to be an issue.

Good product
