This is a nice package of M2 screws, nuts, and flat washers. The variety of lengths is very good as is the quantity of each size, including washers and nuts. As things change in the RC hobby, I can see purchasing an assortment of M3 or M4 hardware the near future.

This is a great little set. Comes with washers and nuts. The tweezers to get them out is really nice too. Just all around great deal.

A stick got wedged into my SRAM derailleur while mountain biking (luckily it was too steep), and completely bent the set screw and snapped my hanger. I couldn't find a good resource to find which exact sized screw I needed, but knew it was within a range of the smaller M* screws. It turned out that I needed an M4 and this kit worked perfectly as a replacement screw... Getting the old one out is a different story.I have also used a few of the screws in various 3D prints and in one or two instances for other bike related stuff, like attaching a water bottle cage.

Did not come with Hex wrench. Had a bunch of washers loose in the shipping envelope. Everything else was as expected.

I purchase this as a go to when I install TV's to wall mounts. Many electonics use M4 or small MM screws. this fits the bill. No more running to the hardware or Walmart to buy a small package of small screws. You will need to purchase washers. They are sold separately. Very good screws and very cost effective.
