iexcell1500 Pcs M3 x 4/6/8/10/12/16/20/25/30/35/40/45/50 Alloy Steel 12.9 Grade Hex Socket Head Cap Screws Bolts Nuts Washers Assortment Kit, Black Oxide Finish

I purchase one of these assortments ever so often to result and this one was like the rest and of good quality not to oily like some I’ve recieved. Perfect.

Pay attention to the other reviewers - the container for these is not useful, at all. Mine managed to survive shipping, but didn't last much longer than that. Otherwise, it's a great assortment of screws for a pretty decent price. They are a touch oily, but nothing a moment with a rag won't fix.

To fabricate machinery.

the screw held fast (to strong recoil) employing minimal torque (and no Loctite) to set it in place

Way cheaper than buying them from the hardware store and great for projects

Great assortment of bolts in various lengths. I didn't count all the sizes, but the item count for the few I did was accurate. If you need "clean" bolts, expect to have to clean them yourself, as they're covered in a light coating of oil (especially the washers and nuts).

Package was crushed and screws/nuts were all mixed up, but that was a shippers problem. All hardware was repacked in one of my personal screw bins, only took a few hours... other than that, hardware was what I expected.

Rolling the screw on a flat surface was wobbly due to the socket head misalignment. The whole set is useless.
