Product Review: M3 Flat Head Wood Screws Assortment Fasteners Kit 420pcs,Phillips Drive Countersunk Head Self-Tapping Screws,Carbon Steel,Contains 20pcs M6 Screw Anchors

 

These are very small wood screws that are useful to use to support small things (like attaching two small pieces of wood together). None of the screws in the set would be useful, for example, as a replacement for door hinge brackets or something along those lines. You do get some drywall anchors to use if needed, but I honestly cannot think of anything you would screw into a wall for which these would be all that useful, because the heads of the screws are also very small.
