Great Bolt Assortment to Have Around
This Kwokker metric bolt assortment is a great set to keep on hand. The M2, M3, and M4 sizes give you a lot of options, and the range from 4mm to 30mm makes it useful for small repairs, projects, electronics, and 3D printing work. Everything is organized well, and it’s convenient having so many sizes in one kit. Great value and very handy.

Good selection of sizes.
I bought these to use with a set of metric screw inserts. They match up very well. I also used them in several other projects where I had to use a nut and that also worked well. I like the selection of sizes and the quantity is sufficient. I especially like that washers and nuts are included so that I do not have to purchase them separately.

They Aren't Actually Rusty
It appears the factory that this product comes from does not oil—specifically—the nuts and washers on the black oxide sets. All of the bolts themselves came coated in oil. Even without the oil, none of the nuts, washers, or bolts themselves were rusty on arrival. That "rusty" appearance coating the inside of the nut & washers bag is just loose dirt & oxide powder from the giant bin at the dirty mill/factory that makes its way into the bag along with the fasteners when they fill them. I just dumped the 6 nut and washer bags into disposable cups, sprayed some WD-40 on them, and then wiped the excess away with a paper towel. You'll see after cleaning the dust off that they have no actual rust on them. They're in good condition and work well. Kind of a pain since they're new, but it only took a few minutes. Black oxide is supposed to have oil applied to it, so you should oil the nuts and washers if you choose either of the black oxide sets. I also recommend reserving the black oxide sets for indoor & dry conditions, as they won't hold up well to wet conditions for very long without rusting (even with oil applied). Grab the stainless set if you plan to use them in outdoor or wet conditions. Overall, this is a great set of fasteners.
