Hex Socket Metric Bolt Assortment, 1713Pcs M2 M3 M4 | 21 Sizes 4mm–30mm Length; 12.9 Alloy Steel, Zinc Plated; Includes Screws, Nuts & Washers and Hex Bits for Machinery Repair

Received In brand new perfect condition. And very well packaged. Very nice bolts, nuts and washers kit. Comes in a nice case. Received today and put it to good use. When needed I would buy again. Lots of sizes. Highly recommend!!

This is a wonderful way to get assorted screws, nuts, washers, and lock washers. I kid you not, I was at one of the big-box hardware stores and they were selling 2-4 screws (size M3) for something like $1.24 /ea. It doesn't take long to realize this is the better deal! They seem to be decently strong and well made, and the little tools (and tweezers!) were a nice touch. Thanks!

Great works perfect for rc

I bought this kit since it had screw that were 25mm in size and this kit didnt disappointed. I like the selection of screws comparted to other kits

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.

Top notch fast delivery good quality

Works as it should

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.
