Amazing value, must have for projects
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!

variety of scresws which help in any situation
Need M screws this is the one. I had to attach an adapter to my Dewalt plunge router which I purchased about thirty years ago. At the time, I did not need the adapter to attach guide bushings. Now I do. To attach the adapter to my router base I needed screws which were correct size. It is a counter sink screw. Unbeknown to me it was metric. I wasted much time and money to achieve my end. I could not wait to find if these worked. They did. I am so happy. Now I can attach guide busing and go to work.

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.

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.

Great Metric Screw kit.
A good supply of metric screws for my projects. The assortment is very well rounded.

Spare nut/bolt kit for emergency repairs
Great kit to have when fixing things around your house or on your vehicle that have missing nut or bolt that vibrated loose and fell off your vehicle
