Hilitchi 420pcs M2 3 4 304 Stainless Steel Hex Socket Head Cap Screws Nuts Assortment Kit with Box (304 Stainless Steel)

SO, I didn't need this many screws. For the project it needed about 20. However, the price for 20 was just a dollar less than this whole case, so here we are.All the screws appear to high quality. I didn't put them under a microscope or caliper, just pulled a few out an screwed them into the M2 holes I'd tapped. They all went in smoothly. All are shiny, no bare spots on any of the threads, no annoying flashing or bits of metal around the heads or elsewhere. The included case was sturdy enough that there were no mixed types in any of the compartments.

Just what I was looking for for my 3d prints. Love the storage box to keep all the parts organized, good quality and nice assortment.

I haven't done any stress testing on these, but they seem perfectly fine. The individual sizes would really benefit from bags or a tighter seal when shipping, as they get mixed together during transport necessitating sorting them yourself when they arrive. It's a great collection of lengths and diameters - these should be very useful for my projects. One thing to be clear on is there are fewer nuts (20 per size) than there are bolts (80 per size), so you're likely going to need to supplement with additional nuts at some point.

This has several matching screw types for my Ender 3 printer. I've since used a few for some of my builds and they're perfect.

Just what I was looking for. Good storage box to keep all the parts in their place.

Great set love Hilitchi stuff!

Not the best, and screws are all mixed up an not neatly sorted like it shows in the picture
