The procedure shown will enable you to fasten materials together with your screwdriver without
stripping, splitting, or separating the material.
1. Clamp the pieces together and drill the first hole 2/3 the diameter of the screw. If the mate-
rial is soft, drill only 2/3 of the proper length. If it is hard, drill the entire length.
2. Unclamp the pieces and drill the second hole the same diameter as the screw shank in the
first or top piece of wood.
3. If a flat head screw is used, countersink the hole to make the screw flush with the surface.
Then, simply apply even pressure when driving the screw. The screw shank clearance hole
in the first piece allows the screw head to pull the pieces tightly together.
2. Drill the same
diameter as
screw shank.
1. Drill 2/3 diameter and 2/3 of
screw length for soft materials,
full length for hard materials.
