Then, select the correct screw thread and head type.
Generally the type of
workpiece you are going to be working with will determine which type of screw
thread to use.
Screws come in two types, fine and coarse thread. Fine thread screws are usually
used for hardwoods and coarse thread screws for softer woods.
Fine thread screws are less aggressive, but ensure great holding power without
splitting the workpiece. Softwoods like pine and spruce are soft and not very
dense meaning they need a screw with deep, wider threads that will bite into their
soft fibers.
Use the table below to see which screw thread type is best for the workpiece
material your are working with...

Mahogany, Maple, Cherry, Ash, Walnut, Teak, Oak, Silver & red

Coarse

When it comes to choosing the screw head type, use washer head screws for
softwoods and pan head screws for harder woods.
