About Countersunk Screws:
A countersunk screw is a type of fastening that sits flush with the surface of the material it occupies.
These screws typically are used so that you can cover them easily with either a screw cap or piece of wood.
Other applications include the need for a fastening not to protrude so other objects can rest upon it stably, or to fasten it further to another object.

I don't know why this is a high return item, the quality is near perfect. the only gripe I have is the sizing chart is not built for old eyes, get a magnifying glass out. 5/5 will buy again when I run out.

Practical combination of lengths for flathead (countersink) m3 screws. They are medium Phillips head in black.

I needed a few flat head 3mm screws for a project. It was cheaper to buy this set through Amazon than than jumping in the car and driving to Lowes or Home Depot or Ace Hardware with the hope that one of them would actually have them. These did the job and are going to be handy to have for other projects.
