  • Gets the job done
Color: C Flat Hex Black Set
Item perfectly as described. I was surprised they even came in individual bags! They have oil on them (probably to prevent rusting) so handle with gloves or with care.

  • They Aren't Actually Rusty
Color: A Black Hex Socket Set
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. ... show more

  • Nice selection
Color: C Flat Hex Black Set
Ordered these nuts/bolts/washers for a project. Actually got more than I expected from other reviews. Mine came with each size in its own bag. I did have to open the bag and put the parts into their bins. No less than expected. The parts were clean, well packaged, and work for the projects I bought them for. Very happy with them. Would buy from them, again. ... show more

  • Everything for playing with small metric fittings
Color: A Black Hex Socket Set
Nice set; everything comes in its own bag, you need to carefully open and put in the slot for it. UNFORTUNATELY: all of the hardware is covered with machine oil. Which gets all over you when you're trying to dump them into their proper places. Either lose the machine oil (When I buy black oxide coated machine screws from a big box store they don't come soaked in oil) or add a nice little slip of paper that says "lubed for your protection" ... show more

  • I screwed up...
Color: A Black Hex Socket Set
I didn't need parts this small but have found uses for them anyway. Really threaded the needle. I thought I was nuts and I almost bolted from this purchase, but it all came out in the washer.
