If you’re not sure which fixings to use for certain jobs, this guide could come very handy to you.
There are flat head, round head and countersink screws. Cross head -Phillips or Posidrive - screws are now the most common and the easiest to work with but there are also a lot of single slotted screws about so you will need a good selection of different size and type screwdrivers. Flat & round heads are exactly what their names imply. You “countersink” for a screw if you want it to be flush with or below the surface when screwed in - to do this you can use a special countersink bit or drill a shallow hole with a large drill bit.
